Dolman IN Somerset England

I have traced my family back to my 6xGG Barnabas Dolman. As far as we know, he was from Somerset, England. Barnabas Dolman was born in 1690. His wife's name was Mary (Unknown). We believe they were both born in 1690 in Somerset. They had three children, Thomas 8, Jonathan 6, and Mary 4 years old who were all baptized on 6 January,1715 at St, John the Baptist church in Somerset. Jonathan was my 5xGG. We are looking for any other information on Barnabas and Mary. Thank you in advance.
