1881 census record shows William Grimsley living in Bicester with wife Eunice King and their two daughters. Also listed is:
George Edmunds age 59 (b.1822) Sulgrave, Northamptonshire. Uncle. Widow. Occ: Major Bengal Army.
Uncle? This only makes sense if Eunice's mother's maiden name was Edmunds? I don't know what it is so could be; don't see how it would integrate into the Grimsley line. I've tried to trace some records to figure it out but not really got anywhere.
