I have checked my files and it does not appear that most of the above
information is sound. First off, Margaret, wife of Sir Thomas Carrington, can
not possibly be the daughter of Robert de Roos of Gedney. The reason for that
is simple. His IPM shows that he died in 1381, without issue.
As for Robert de Roos's grandparents, I find that they were Robert de Roos and
his wife, Ernebruga (not Gremburga). I seriously doubt that Erneburga was the
daughter of Robert Constable of Flamborough, Yorkshire. If anything, she was
the daughter of Simon Constable, of Halsham, Yorkshire, who conveyed his
one-third interest in Gedney, co. Lincoln as one of the d'Oyry co-heirs to
Robert and Erneburga, probably as Erneburga's maritagium. My sources are The
Genealogist, N.S., 9:7 and 10:90, which sets forth information gleaned from the
Plea Rolls.
If anyone has any further information on the Roos family of Gedney or their
potential link to the Constable and d'Oyry families, please contact me.
Thanks!
All for now. Sincerely, Douglas Richardson
