Hi Rustine, and welcome to WikiTree. The first thing I would like to say is why pay for information when you have so many people that are willing to help you get it on WikiTree, and you don't have to pay a dime?
Frank Gill says that Franz Joseph already has a profile here, so maybe you just need to start researching your own family and see where it leads you.
Will Palmer has also given you some excellent sources so you already know how friendly our community is.
Good luck on your search, and welcome to WikiTree again.
