I think you're looking for a needle in a haystack. First you need to develop your haystack. If you don't have any more information about Joseph Weigle, how do you know about him? Who are his children? If you make profiles for anybody you know that could be connected to him then clues can be sought to learn more about him. Since Nebraska didn't become a state until 1867 he wouldn't have been born in the State of Nebraska, although he could have been born in the territory.
