Hi, I am another great grand-daughter of Edward and Catherine, my grandfather was Peter who was Sarah Ann's younger brother born 1873. I have been trying for years to find out what happened to Sarah Ann. I was also wondering whether or not she was Edward's daughter, as Catherine was previously married to a Henry Hughes (Edward also was previously married to a Margaret Small and had a son John to her born 1851). Edward & Catherine did not marry until 1865, so presumably one or both of their first spouses were still alive until then.
