Jeremiah feels very heavy and biblical, much more so than
Jeremy. It can feel either very boorish or magnanimous. If I were to be conservative, I'd go with
Jeremiah Peter,
Jeremiah Levi, or
Jeremiah Felix, and if I were to use middle names that were less conventional, I'd go with
Jeremiah Wilfred,
Jeremiah Humphrey, or
Jeremiah Rupert.
