Tripp

Tripp developed as a nickname that can indicate someone who is the third in a family to bear the same name. That naming custom is different from being the third child. Tripp is also used independently as an official first name, without any requirement that the family follow that tradition.

The doubled p distinguishes it visually from the ordinary English word trip, although the sound is the same. Families choosing it to continue a namesake tradition can keep a longer inherited name formally, or choose Tripp itself. Its single syllable gives it a concise rhythm beside a longer surname and leaves little need for further shortening.
