I do not have anything about parents of Dr. Samuel Smith. I have the following siblings:
Margaret, Sarah and William who immigrated with him, and John and Robert who stayed in Ireland. I assume his parents either stayed in Ireland, too, or died before he left.
My husband also descends from Henry Smith and his wife Jane Watson (daughter of Samuel Watson and Catherine Jordan) through their son Jackson Smith and wife Mary Matthews, through their son Scipio Americus Smith who was my husband's grandfather.
I've accumulated quite a bit of info on both Smiths and Watsons, and would like to communicate with you via e-mail and exchange information.
How do you descend from Henry Smith?
