Polly had 3 children. Paul Blanton Brooks, now Covert as he took his father's name (I believe) He lives in Texas around the Austin area. Ira Yates, which I believe was Polly's maiden name, and lives in Austin and Claire- don't have her married name or her maiden name. Polly was from Iraan Texas, named after her father or grandfather. Been a while since her son told me the history.
Hope this helps.
