I have arms recorded for three entries (for two different arms) in the surname of TRIPP, but none for a John TRIPP. To assist you, we need more information. Just a few questions:-
1. Have you had a look at http://www.sog.org.uk/leaflets/arms.html
2. How do you know that he had a coat of arms?
3. Do you know his paternal ancestry?
4. Any dates or place of orign?
If you can provide some of that info, we'll see what we can find for you.
