The Atwood connection is very interesting. However, I have a question that perhaps you can answer. All the census records, church records of this line of people spell the last name as sproUt. I know there are also people in Lancaster county that use the sproAt spelling. You also refer to your Joseph and Robert as sproAt, yet all the records I see they spell their own names as sproUt, even as early as 1790 and as late as 1890. Are these people of the same family group and only misspelling through illiteracy???? Are they blood related? How far back can you go until sproUt becomes sproAt???
