Look at death date of the wives. I have several female ancestors who died in or shortly after childbirth. The husband married almost immediately because he needed help with the kids - especially if one was an infant. Remember - childbirth was a prime cause of death 100 years ago.
Thanks for the great tip. Unfortunately, the case I am referring to does not have a death date for the wife. I will keep searing.
It wasn't uncommon for the same name to appear twice, it often happened if the elder child died and the new babe given his name, another alternative is if after the death of the first wife some of the children went to other relatives.
When tracing my family I found that there was two entries for the marriage of my Great grandparents, all details accurate except in one the spelling of the surname Harvey and in the other Hervey. Great grandfather had a very thick Irish accent
Thanks for contributing to my growing knowledge bank regarding finding the correct relatives. So many things to consider when reading records and discovering the possible "why" of same name usage.
