Y Chromosome results
The Y-Chromosome has definable segments of DNA with known genetic characteristics. These segments are known as Markers. These markers occur at an identifiable physical location on a chromosome known as a Locus. Each marker is designated by a number (known as DYS#), according to international conventions. You will often find the terms Marker and Locus used interchangeably, but technically the Marker is what is tested and the Locus is where the marker is located on the chromosome.
Although there are several types of markers used in DNA studies, the Y-Chromosome test uses only one type. The marker used is called a Short Tandem Repeat (STR). STRs are short sequences of DNA, (usually 2, 3, 4, or 5 base pairs long), that are repeated numerous times in a head-tail manner. The 16 base pair sequence of "gatagatagatagata" would represent 4 repeats of the sequence "gata". These repeats are referred to as Allele. The variation of the number of repeats of each marker enables discrimination between individuals.
It is quite a challenge to explore your haplotype and ascertain one's genetic origins with a hap tester: http://www.hprg.com/hapest5/hapest5b/hapest5.htm

EUSTACE FAMILY
The Eustace Family Y chromosome study has led to an unexpected correlations. There are living relations in Niagara Falls, Paul Eustace EY66 who is 2 markers different than ours. Then there are a set of four individuals with closely similar profiles, Peter Eustace (Thunder Bay ON), Alan Eustace (ON), Charles Declan (Louth Ireland) and Noel Eustace (New Brunswick) who are different on 3 markers. Noting the similarities Marilyn Clark, sister of Alan and cousin of Peter, decided to explore where we all fit. Together we suggest some startling information on the subjects of our ancestors.
EARLIER GENERATIONS
Great-Grandfather John [Joseph] Eustace was born about 1835 in Ireland. He married Philomene Rendewer who was from Quebec, born about 1845. Their wedding must have been about 1862 or so. Her parents' names were:
Father: Francis Rendewer (or Round) which is likely where your grandfather's name came from
Mother:Margaretta Nean.
They had 5 children before John died in an industrial accident June 19, 1879 in Hamilton, he was a labourer.
Death certificate is # 015350.in that I found:
1. John b 1864, St. John, N.B. He married on Dec. 25, 1885 in Hamilton, an orphan named Jenny Tweedle. He was 21 and an ironworker. Jenny was from Stony Creek.
2. Robert, born in St. Mary's, QC. about 1870. He married September 15, 1902 in York Co., which is part of Toronto. He married Joanne Daly from England. They were both 32 at the time.
3. Mary Anne was born in 1867.
4. Alice was born in 1877.
5. Francis who was born August 2, 1876 in Hamilton. Francis (Frank) married twice-- Merritt Theresa (Maude) Thornton in June 30, 1902 and Madelaine Miller.
PHILOMON RENOWER EUSTACE (CAHILL)
John's wife, Philomon, remarried in 1881, Michael Cahill, from Ireland.The date is 23 Oct. 1881.
MAUD THORNTON EUSTACE
Meanwhile, Maud's family immigrated to Canada from Ireland in 1883-84 (I've seen both dates on census information). It may
be her father James Thornton came first (June 22, 1881) aboard ship "Canadian" (see attached from Toronto immigration office) and then sent for his family.
Her mother was Delia Roberts. She remarried after James died (date unknown so far). Her second husband was David Vint.
They had a daughter Mary in 1885. Maud or Merrit is listed as a member of Church of England and was a domestic in 1901 before she married Frank.
NIALL OF NINE HOSTAGES
The Eustace family saga of this branch seems to trace back to to the story of Niall of Nine Hostages, the Irish warlord, by way of the much ballyhooed misunderstanding between Professor Henry Louis (Skip) Gates and Officer Sergeant James Crowley. As you might recall, the two men took part in a confrontation that resulted in the famous ‘beer summit’ on White House grounds in 2009. Did you also know that the two men are distantly related? Gates is one of many famous African men with Irish lineage. Sargent Crowley traces his roots in Irish ancestry to one Niall Noigiallach, the same as Professor Gates. http://abcnews.go.com/Politics/Story?id=8195564&page=1
Niall was the fourth and fifth century son of the Irish High King, Eochaid Mugmedon, and the daughter of the then British king. He established a wide and powerful kingdom extending to portions of Wales and France. Niall is said to be a ruthless warrior often kidnapping members of royalty from conquered lands. These hostages became part of his court either willingly, as courtesans, or unwillingly, as prisoners. Niall reportedly fathered twelve sons, many were kings in their own right.

We compared our Y chromosome alleles and found Declan Eustace of Dublin, Ireland match Niall (reported) haplotype on 12 of 12 markers. Of the same 12 alleles, Dan matches 10 alleles with two alleles being different one marker more and one marker less. We seem to be from the same genealogical branch traced back to Declan.
The science informs us that there is a 50% chance that our Most Recent Common Ancestor is as close as 31 generations ago; 90% chance that he is 61 generations, using the most optimistic methods. [Reference: MRCA = most recent common ancestor
12 tested 2 mismatches, each one unit off
50% probability 31 generations
90% probability 61 generations
[data uses Walsh, Genetics 158, 897 - 912 (2001)]
It is interesting to note Niall lived approximately 62 generations ago.
Tracing back our Canadian roots, Marilyn shared a photo of her great grandfather, John Henry Eustace (18xx - 18yy). John Henry had some resemblances but did not appear the same man as a photo we believe to be of John Joseph (b. ~1835), Dan’s great grandfather who hailed from Dublin, Ireland.
Famous descendants include Niall's great-great grandson Saint Columba, Saint Máel Ruba, the Kings of Scotland, the Kings of Ailech, the Kings of Tir Eogain, the Kings of Tír Conaill, the Scottish Clan MacNeil and the current British royal family.[citation needed]
In January 2006, scientists suggested that Niall may have been the most fecund male in Irish history, and second only to Genghis Khan worldwide.[citation needed] In northwest Ireland as many as 21.5% of men (8.3% in Ireland in total) have common Y chromosome haplotypes that lay within the haplogroup R1b, with a common male line ancestor roughly 1500 years ago.[13]
Y-DNA Haplogroup R1b1b2e, formerly R1b1c7 also identified as R-M222, was shown to be especially common among family names which claim a descent from Niall. The sample population consisted of the following surnames (and sample number): (O')Gallagher (12); (O')Boyle (9); (O')Doherty (5); O'Donnell (4); O'Connor (3); Cannon (3), Bradley (2); O'Reilly (2); Flynn (2); (Mc)Kee (2); Campbell (1); Devlin (1); Donnelly (1); Egan (1); Gormley (1); Hynes (1); McCaul (1); McGovern (1); McLoughlin (1); McManus (1); McMenamin (1); Molloy (1); O'Kane (1); O'Rourke (1); and Quinn (1).[14]
