None needed--the Hignells and Dimonds were a very confusing bunch. For example, once the Dimond offspring came to America, they would switch their first and middle names at the drop of a hat. There are censuses where Charley becomes Walter, and others where he is Charles. If his Mother, Mary Jane Dimond hadn't been a part of the household, I wouldn't know who was who.
My Great Grandmother, Mary Elizabeth Riley (Dimond) used Elizabeth as a first name: Mary in others. If it hadn't been for her Husband and children, I wouldn't know if she was my great grandmother.
And people were far more casual about giving their ages.
I have admiration for Mary Hignell--were there many Lady Sextons in 19th century Wales? I bet she was a tough cookie.
