Well, I had a wonderful turkey day dinner with lots of family, now I'm soporific, but wanted to complete my answer to you. The direct ancestors who left Aghadowey were Blairs, headed by Robert and his wife Isabella Rankin. They were accompanied by James Blair, the elderly father of Robert, and a hero of the siege of Londonderry. Robert's mother had been the late Rachel Boyd, daughter of James Boyd, Lord of Kilmarnock, and his wife Catherine Creyke. They were residents of Aghadowey. The younger family sailed from Belfast, I think, on the ship "Robert" in the spring or summer of 1719 for the city of Boston.
I'm having a lot of fun practicing my pronunciation of Ockadooey.
Thanks
