Felts
A surname most likely tied to felt-making or felt goods, though the historical evidence here is thin.
The #5,267 most common surname in the United States (2010 Census) — about 1 in every 46,631 Americans shares it.
Etymology
Felts is most plausibly an English occupational surname connected with felt, the thick matted cloth used for hats, garments, and other goods. In origin, it likely referred to someone who made, sold, or worked with felt. The word itself comes from Old English and older Germanic roots meaning the textile material, so the surname is straightforwardly descriptive of trade.
History
As with many English trade names, Felts could have arisen independently in more than one place from the same occupation. The modern spelling may also reflect a pluralized or possessive-looking form that stabilized over time. The single excerpt provided does not give a direct dictionary explanation for the surname, so this should be treated as a careful inference rather than a firm historical statement.

Fun fact
Because felt was such a common practical material in preindustrial life, surnames built from it could emerge from several different trades or shop roles.
