You can find "Acre" England in a Euro-Atlas for Great Britain. It is published by American Maps which is a part of the Langenscheidt Publishing Group. The price is $16.95 on the cover. I bought it at the local Barnes and Noble, but it is probably available at other bookstores.
The Atlas is on the European version of 8.5 by 11 inch paper, i.e., it is 8 by 11.5 inches. It has 100 pages of detailed maps of Great Britain (England, Wales, Scotland and Ireland), and a 35 page index. There are 14 pages of maps of the largest cities. On a less detailed map such as you would find in a typical world atlas, you would be looking for Blackburn and Burnley. Acre is about halfway between the two, and a smidgeon south.
There is no indication of population in the Euro-Atlas. But Acre is in the smallest possible letters in the detailed local maps. That probably means that if you sneeze while driving through Acre, you might miss the entire town.
Ayekerley looks to me like it would be pronounced as if it had a long "A."
There is a Virginia family that spells the name Ackerly. They trace their ancestry from the German Akerlein, meaning like a field. Aker=field, lein=like. One of the family patriarchs spelled his name Akerly. The family claims other spellings including Akeley, Ackley, Ackeley, Ackerley, Ackerly, Akerly, Acly, Akely and Akley. They claim the Ackerly family of Brookhaven on Long Island as their ancestors.
