HI!
It helps that you have his year of birth, but we cannot tell from your message if you know anything about where he lived, so forum members do not know where to search.
Please also tell us what information you need help with - searching takes time, and folks do not want to waste time tracking down information you do not need as you already have it. "Any information" covers a lot of territory.
What do you already know about these people in addition to their names and relationships to each other?
