Hello everyone, I am looking for some information regarding some distant ancestors:

William Garrett (born c.1785-c.1866), Lezayre
Judith Killip (c.1781-1852), Lezayre
m. 20/03/1808

They had at least 4 children: John (b.1816), William (b.1819), Margaret (b.1823) and Ann (b.1814).

I am trying to extend the family tree upwards, so any knowledge of their ancestors or families would be highly appreciated.

Thanks
J. Garrett
