HI, this is the information I have on the other children of James and Henrietta. I do not not dates or places or birth or death for them, sorry. I would think they were all born in Upsur TX, but have not looked into it yet, sorry. I just got this information in the past few weeks and have been out of town all week.
I do not know if it will help you or not. Hope so. If you find a connection let me know. I can use all the help I can get!
