Here are a few ideas:
Mitchell - "M" from Martin, "ich"-sound from Richard
Michael - "M" from Martin, "ich" from Richard (different sound though)
Tristan - "Ri" from Richard, "tin"-sound from Martin
Ryan - "R" from Richard, n-ending from Martin
Charles, Gerard, Harvey - have the a-r sequence of both Martin and Richard
