wow, this is great, I would love to get pictures!!! Rebecca who has also posted on this message board is also part of the family. She actually just visited Patricia Gillaspie (my mother-in-law) this weekend and we just put it together that we had already been communicating through this website.
Yes, so far I have found that Andrew and Etta May had five children. All four that you mentioned plus Mary V who died at only 10 months old. She is buried in the Powell Cemetary. The headstone says daughter of AJ and EM Gillaspie so I assume this is their daughter. Charles Grant Gillaspie( 1 of the 4 children you mention)had several children, one of them named Andrew Jackson Gillaspie. Andrew Jackson is the father of Patricia Gillaspie.
I will get more information to you.
