I am looking for information on this couple. They emigrated to Wisconsin from England sometime between 1852 and 1860, settling in Dodgeville. According to an article I have on their son, Thomas (my great-grandfather), Mary died in 1894. Henry was still alive at the time the article was written (about 1910 or 1911) and may have moved to Michigan. I also know that Henry at least declared his intention to become an American citizen because I used to have a copy of that record (I am in the process of trying to get another copy). I have been unable to find records of either person's death. I know I need to get copies of census reports (again), but any help would be greatly appreciated.
