Hi. Samuel Tygart (1775,Ohio) is my gggg grandfather. I'm trying to write my family tree but unfortunately I got stuck with Samuel Tygart who was married to Elizabeth Sammas in Ross County, Ohio (1804). Is there any relation between David Tygart (Tygart Valley) 1753 and Samuel Tygart 1775? Why was David Tygart sent to the United States for? Is there any info about him before 1753? Any info please contact me. Thank you very much.
