Crummey is a variation of Crombie, a Scottish place name from the so-named location in the former county of Aberdeenshire, now in the Grampian region.Other variations include Crumbie, Crummie, Crummay, Crummy, Crumey, Crumy, and the (o's) Crombie, Crommie, ect. Though the spelling is different the sound is the same. Crom(b)ie means crooked.Spelling variations of this surname causes much confusion in research. These changes occured for a variety of reasons, sometimes a different spelling indicated a religious or clan loyalty to a branch or chieftain. Sometimes it was just mis-spelled as sometimes seen between father and son. It is not uncommon for a clansman to be born with one spelling, marry with another, and yet another to appear on his headstone. Most Irish Cromies, Crummys, ect. are of Scottish descent. James Crombie received estates in the barony of Glenarne between 1600 and 1700 when the locale population of Irish Catholics were moved out of the counties of Antrim and Down. John Cromie was prominent amoung the defenders of Derry in 1689. That Cromies may also be Irish Gaels is indicated by the fact the Petty's "census" of 1659 records five families of O'Cromy in the barony of Armagh. A Fiant of 1602 mentions Teig McConnogher O'Cromy, yeoman, of Dromkarra ( Co. Cork). In the previous century O'Crome and O'Croyme occur in counties Meath and Galway and may be earlier forms of the same name. The earliest known Cromey in America was Thomas, who settled in Virginia in 1638. It is my hope that this information will help others in their search for their ancesters with this often mis-spelled surname.
