Hi John
Not meaning to repeat what has already been said but a few more details would help the search to help you start in the right place
If you can let us know the approx date of birth for each man, the relationship to each other, any other relationship you might be aware of and finally what you are really hoping to locate - "looking for anything" is a very wide band! Is it more important to you to find, ancestors, siblings, descendants, etc.
Once you steer us in the correct direction we can start to help accurately
