The information you give is very very general. You would be well advised
to seek information on your family by searching through the US censuses,
obtaining his naturalization papers (which depending on the year may
give you a location to deal with), and possibly other papers. You can
read the information on my Hints page, url below, to help you.
We'll help you however we can of course, but you'll need more details to
go on. Why don't you post more of what you have done, or what
specifically you are looking for?
