I grew up thinking my paternal grandmother's name was Nellie.My Dad's cousin who lived near us always called her Aunt Nellie.I was surprised to find out her name was Mary Ellen.You never can tell when and where people will use their nicknames, either.That grandmother and her husband, my grandfather, both used their nicknames on their marriage record.I would have thought in 1905 people would be using their "legal" names on official records.They were quite a bit older then my maternal grandparents.
Keep in mind most of the information is still in the clue stages, don't throw out anything, yet. You could always obtain a copy of the SS application for the Belle Sutton, it should have the names of her parents on there.
Also, they trip us up by swapping back and forth using first name then, middle name as first name, sometimes back again.My gr gr grdfthr had a brother the family always referred to as Miller Rice.Turns out his name was Adam Miller Rice, and on the first census he was out on his own he was listed as Adam M. Rice, next one as A. Miller Rice and then just good old Miller Rice.
You really have to be a detective and watch for the clues. (^_^)
As far as William being retired, have you checked land records?When did he sell his land?Or, did his heirs sell the land?If so, all heirs would have to sign off to give clear title to the buyer.Land records are often overlooked and many times can be a very helpful source in researching.I love using them.Land record books sometimes have other records recorded in them, too.
Keep talking with that aunt, sometimes old events will pop up in memories, especially if you get them to reminiscing.One event sometimes can trigger another one and the oldmemories start coming back.Instead of asking just point blank questions, try a given subject.What was it like when she was a little girl going to school?Who lived around them then, or who did they go to visit?Did the family get together for birthdays or holidays?Who attended family weddings or funerals.Get her started on the good old days trail.See what I mean?
