Force brute

Last night I was in a party at 42, chill, then after a few drinks, I managed to get the password of uncle Niel !!
Well, he didn't want to give it to me directly but he sent me its MD5 hash saying that I will never crack it hu hu hu ...
After a few investigations and a little forcing, I ended up knowing roughly its composition, here is the order:
- A number between 0 and 42
- One of the company he founded
- His rank in the top 50 of french fortunes
- The first name of a close member of his family.

Every word/name begins with a capital letter. Let's make a wordlist and try !

Here is the hash : 55d91e34650fd1a804cd94f5f39b34fb

Tips

If you have more than 17 years of your life to lose, you can try to crack it with something else than a wordlist you generated.
And yes, some values may change over the years, but it will not be a problem for this challenge.
