Hi Mike, I wish I knew the answer to that...The census in 1840 & earlier just have the name of the head of the house & then how many at the different age levels... Sooo, I have to find another source & I haven't found one as yet... I just know that George Flack was born in 1794, he married Sarah Groves & had 8 children... I know what the kids names are & that my son's Great Grandfather is George & Sarah's youngest child, Miles Flack, from his second marriage)...If you find a way to connect George up with Benjamin Please let me know... Or anyone else...Ardyce
