Relationships
Father: Gervase, count of Rethel.
Mother: Elisabeth de Namur.
Todd Farmerie, in a post from 8/5/07 to soc.genealogy.medieval, notes that Moriarty made a convincing argument for these parents in an article in The American Genealogist xx (January, 1944), 255-256, which I have not seen.
Spouse: Robert de Marmion (died about 1144).
This relationship is given by the Oxfordshire VCH (12: sub Stanton Harcourt), by Keats-Rohan (p. 378), and by the Complete Peerage (8: 506), which states that Millicent’s parentage is unknown.
Spouse: Richard de Camville (died 1176).
Vincent (ODNB), the Complete Peerage (8: 508), by Keats-Rohan (p. 378), and the Oxfordshire VCH (12: sub Stanton Harcourt) state that Richard married Millicent, the widow of Robert de Marmion. This relationship is recorded in the Cartulary of Eynsham (1, no. 584).
