HI Sue, Thanks for your post. I am interested in descendants of William and Susannah Brightman, through their son, Thomas. He is believed to have emigrated to South Carolina 1776-1790. One version of why he left RI is that he fought for the British during the Revolution. After the war, his first wife (Mariah - maiden name unknown) and several of his children died in RI. Being both unpopular and grieving, he left for SC. There he married the twice-widowed Lydia Logan Heard Wardlaw. I am descended from his son George, survivor of the first marriage.
If you have any information about Thomas, particularly the last name of his first wife, I would appreciate receiving it. And glad to share whatever I have.
