Frederick was 19 when he married Emma Grace who was only 15. He was a dentist. Frederick left Rochester, NY in 1889 when their daughter, Maud, was only five years old. I do not know if Emma and Maud went with him. Emma remarried at the age of 33 on September 12, 1901 to Nicholas Heffner. This was the second marriage for both Emma and Nicholas.
In the 1902 RCD Nicholas Heffner was listed as a brakeman with the N.Y.C.R.R. and was boarding at 174 Brown which was the home of Emma's parents.
Fred does not appear again until the 1930 Census in Chicago, Illinois with a wife named Ruth. Fred is listed in his brother's obituary (Peter) in 1931 as living in Chicago. Fred is not listed in his sister's obituary in 1933 (Margaret Steimes).
The last time Nicholas Heffner is listed is the 1908 RCD. I can not find any more information on Emma and Nicholas Heffner. There is a Nicholas Heffner buried at Holy Sepulchre, but I can not verify that it is the same person and I have no death information for Emma.
Fred and Emma's daughter, Maud, married Albert Hall on December 17, 1903. The 1910 census shows that Maud and Albert are living with Maud's grandparents (Thomas and Jennie Grace) at 174 Brown Street. These are Maud's mother's parents. Albert Hall died on December 19, 1910 at the age of 33. I can not find any further information for Maud after the 1911 RCD. I don't know where she or Albert are buried.
