Which parish for John Dooley from Menlough?

Hello, My name is Tom Dooley and I live in Michigan in the U.S. My great, great grandfather was named John Dooley and it is reported that he came from Menlough, Co. Galway. He was born around 1829 and emigrated to New York in 1847. He married Ellen Cunningham upon arrival in N.Y. and is buried in the town of Wyoming, Lambton County, Ontario. 

I would like to know which parish Menlough is a part of so that I can continue with research. 

Thank you.
