I've been very interested in Sarah Ector for quite awhile now.First found record of her at the North Ireland records site.You might be interested in visting that website which has a short history on John Dunlap, her son.
Go to: http://proni.nics.gov.uk/http://proni.nics.gov.uk/ Click (on left) Records Heldthen scroll down to Private Papers and click.Then click on Dunlap/Delap papers.
Do you have any other children's names for her or parents or siblings?
There is record of a James Ector in County Tyrone, in Camus Township sometime in the 1700's.There is also a Margaret Ector there who married William McCreery shortly before 1850.Alexander Ector Orr was born in Strabane, Tyrone County in 1831 and migrated to America in 1850.
Obviously, Ectors were long time residents of County Tyrone.The question is how to get birth records, marriage records, etc. from Tyrone to see if Hugh, Samuel, etc. are related to the Tyrone County Ectors?
