The Montgomery Baptist Church source shows her being received into that congregation from the congregation in Llanwenarth in 1722. I used that congregation location as an "uncertain" birth location. The Berks County History source describes her tombstone in passing during a description of the ruined graveyard at the Tulpohocken Baptist Church site. Serendipity. The stone gave her death date and age for an "uncertain" birth year. I will put that info in the comments.
Thanks for your reply.
