Hi Steve, Just now seeing this posting in which you tell me Christina's parents. Unfortunately, Christina and Benjamin did not have a James, but he could be related nevertheless, maybe a cousin to Benjamin.
When Benjamin and Christina md in 1863, the names of Benjamin's parents were given as Benjamin Marshall and Margaret Crawford. He was born in Glasgow, Lanarkshire abt 1835. Christina or Christian was a very common name that was passed on in the Blue/Bell family. The names you mention are unusual to my line, but then, I havent traced Benjamin's back yet. I do know that Scots added an "ina"on the end of the given name if a girl was born and they wanted to pass on the name, for instance, my aunt Jimmy was called Jamesina. I will do a little more looking into the family and pass on anything relevant to you. regards, Jan
