1871 Census - Joseph (47) and Catherine (37) Bonner are together with their family.
1879 - Joseph dies (55)
1880 - Joseph's daughter, Catherine (21) marries Peter Diamond (25)
1881 Census - Peter and Catherine now have a son, Joseph Bonner Diamond.
1881 Census - Catherine (47), Joseph's widow and her remaining children are together, but she has been listed as Catherine DIAMOND, while her children are all Bonner's!

How did Catherine end up with her DAUGHTER'S married surname?
