Hi Sonas,
Thank you for your reply. Have used Ancestry and come with that Isaac Mann adopted Frances, Henry & John around 1765 as their parents had died.
Isaac was the brother of their Father Samuel.
Frances married Christopher Townsend in 1776
John married Mary Smyth in 1771
Henry married Jayne Smyth in 1767.
They were all married in Cloyne, Ireland. Isaac never married.
Will continue my search on Mann family but, will take time as I am only a beginner.
Once again many thanks for your help.
Regards,
Kiddo
