Where does the surname Aid come from?

Q: My grandparents' name is Aid. I know that my grandpa Frank's mother was named Katie Aid. I have been told she was Irish but when I look it up, I never find the name Aid anywhere in Ireland. Any help would be great. Thanks. I guess I should have said that a former spelling of the name was Ayd.

A: Could have started out a gaeilge name.The British frowned on using Irish and it might have been changed to Aid then. There are some Ayd's here who arrived from Ireland http://search.ancestry.com/cgi-bin/sse.dll?rank=1&tips=0&gsfn=&gsln=Ayd&=&gsby=&gsb2co=3250%2CIreland&gsb2pl=1%2CAll+Counties&gsdy=&gsd2co=1%2CAll+Countries&gsd2pl=1%2C+&=&=&=&sbo=0&sbor=&srchb=r&prox=1&db=&ti=0&ti.si=0&gl=allgs&gss=&so=3 Another interesting site http://ifhf.brsgenealogy.com/surnames.php?surname=AYD
