wow! thank you, Tom.
My husband is related through Wilhelm and Sophia's daughter Maria Elizabeth Wilhelmine who married John Bartholomew Doell. I only have 7 children listed for W & S. I do have access to a picture of the two of them. My husband's family has always said that the last name was changed from Hell to Hall on immigration (which i have not found to be true so far) and also that william was a minister (also not true so far). they even have a very old book by Martin Luther that was printed in the 1500's that was supposed to be one of a set of seven books and has been passed down from generation to generation supposedly from William's family. No idea how that all fits in with anything!
i have found 2 land patents for a william/wilhelm hell in 1844. one in washington co and one in milwaukee co. i also have census images for them for 1850, 1860, 1870, and 1880 all in Mequon, Ozaukee co.
they are a bit of a mystery for me. thank you for helping me clear up a few things. if i have anything you need, just let me know, i am happy to share!
