Hey Randy, this will be a bigger project I'm afraid. As for the name. Seidel comes from "Siedler" (settler) and therefor is more common in the eastern part of Germany since the migation in the middleages took place from west to east and the name "was created" where they settled down. But there is a little chance, that the name is Seitel, if it is derived from the medieval nickname of "Seyfried" which would be "Seitel". This would typicaly have taken place in the west, where this name was common. Unfortunately in the timeframe and region we are looking at, BOTH variants are possible, as you can also see at the name distribution map here.
So I took a quick look at the only "given" source we have, which would be the marriage of the daugther Maria Dorothea Seitel, as given in her profile. She was married on January 11 1724 in Langensoulzbach. I found the original entry here. It says:
Anno 1724, den 11. Jan. seind in der Kirchen Sultzbach öffentlich copulirt, Hannß Michael Haudenschild, weyl Diebold Haudenschilds gewesenen Schäffers zu Niderbronn nachgelassener ehelicher Sohn, und Anna Margaretha, Hannß Adam Ruchen, Schäffers zu Sultzbach ehle. Tochter.
Translation: In the year 1724, on January 11th, got publicly married in the church of Sultzbach, Hans Michael Haudenschild, leftbehind legitimate son of the late Diebold Haudenschild, formerly shepherd in Niederbronn, and Anna Margaretha, legitimate daugther of Hans Adam Ruch, shepherd in Sultzbach.
So this doesn't fit from the names exept for the husband. Unfortunately I only then realized, that also the dates make no sense, since both bride and groom are sayd to be born around 1725/30 ??? So for now I am not sure if there is any evidence at all for this couple to be real. How far have we to go back to hit solid ground here?
------------------------------
EDIT: I think the husband Johann Michael Houdesheld is ok. BUT there is a mixup with his namesake father. The marriage of the parents obviously is copied to the son. And we do not have any clue for the wife of this son at all. As far as I can see he might as well got married in America.
Hope it helps to fix this ...
