I do not know where you acquired this lineage...but it is very much wrong....I am the great-great grand daughter of Dr. John Thomas Clark and his mother's name was Sarah Bradshaw and his Dad was also John Thomas Clark who died at age 24....I have his photograph taken during the Civil War and his age would not reflect that of someone 50 some years old.....I also have a lineage back to 1740 that does not fit with your research....so if you would like to compare your tree to mine or check the one I have on here....please take a look.....I am Sue Fulcher from North Carolina with a Leary/Clark linege back to Pamlico County to York Territory and back to Craven County...
