Acker
Acker is most likely a surname for someone associated with a field or an acre of land, and in some cases may also reflect an oak-related place-name.
The #3,400 most common surname in the United States (2010 Census) — about 1 in every 29,351 Americans shares it.
Etymology
The name is linked to words for a field or acre, especially Old English or Germanic forms behind English and German surnames. Some older writers also connected it with oak-based forms, but the field/acre sense is the clearest and most common explanation in the evidence here. In German surname formation, similar names could arise from places called "Acker" or from a farmstead identified by a field.
History
The sources show Acker used both as a surname and as a family-name element in Germanic naming patterns. English writers in the 19th century sometimes treated Ackers as a Saxon or local name, while German onomastic work points to names formed from place descriptions such as fields or farm plots. The surname is found today in several spelling forms, including Acker and Ackers, and it has also been used in compounds like Ackerman.

Fun fact
A 19th-century source tried to explain Acker as either a field-name surname or a character-trait name tied to the sturdiness of oak, showing how often old surname explanations overlapped.
