Wow, I'm a descendant too. I've been trying to find info about John Teague's father. All the trees list William Teague as his father, but the dates are all wrong.
But what's really interesting is, I live in Accomack Co. I didn't know Purcell was from here. The geneology records are quite good here.
Please send me all the info you have on this family and I'll go to the courthouse (oldest in the US) and see what i can find for you (us).
