Maroney
A surname of uncertain origin, likely an Anglicized Irish name that was reshaped in English spelling.
The #7,568 most common surname in the United States (2010 Census) — about 1 in every 70,329 Americans shares it.
Etymology
The available historical excerpts only show Maroney as a listed surname form, not its derivation, so the exact root is not secure from the provided evidence. In general surname reference works, Maroney is often treated as an Anglicized Irish name, but the spelling has been unstable enough that several Irish source forms have been proposed. The ending -oney is consistent with English renderings of Irish surnames, but the original Gaelic form is not certain from these excerpts alone.
History
Maroney appears in English-language surname lists by the mid-19th century, showing that the name was already established in printed record by then. In modern usage it is found chiefly in the United States and in families of Irish descent. Because the excerpted source material is only incidental and offers no etymology, any deeper historical claim should be treated cautiously.
