I am looking for the parents/siblings of Mary Cockroft b: 1827 in Shelf, Yorkshire, England. She married Joseph Oddy b: 1826 in Southowram, Yorkshire in 1846 in the District of Halifax, Yorkshire and had 6 children with him. She died in 1911 in the District of Halifax. I am looking for her as she is noted on the Death Certificate of James Robinson as his "cousin". James is a long standing brickwall of mine.
I have followed her and Joseph Oddy through the census's looking for a Robinson connection to no avail. There are at least 3 Mary Cockroft's in the 1841 census that could be her but I cannot narrow it down.
Any help or suggestions much appreciated.
