Sipe
A surname most likely reflecting a German name that was Anglicized into a shorter, simpler spelling in America.
The #5,791 most common surname in the United States (2010 Census) — about 1 in every 51,682 Americans shares it.
Etymology
The surname Sipe is usually treated as an Americanized spelling of a German name, and the excerpt specifically equates it with Seip. In German-American surname records, such forms often come from the personal name Seib/Seib(e) or related spellings, though the exact original source can be hard to pin down from a brief citation alone. The main point is that Sipe is likely a phonetic Anglicization rather than an independently formed English surname.
History
The name appears in American records as part of the broader pattern of German surnames being simplified or respelled after immigration. The cited source groups Sipe with other German-to-English surname correspondences, suggesting it was recognized as an adaptation rather than a separate native English form. Today it is a relatively uncommon surname in the United States.
