Simpson (from Simon) is an interesting one. Most of the consonant adjustments are for simplification (e.g., Robkins -> Robins, and Adkins -> Atkins) but expanding Sim to Simp seems like an outlier in this sense because Simson doesn't seem particularly difficult to say. I believe dropping the /p/ is common, even, depending on the dialect.
