Any info Chandley was a Dentist

My grandfather was George Albert Chandley, born 1904.  I had always heard that he had and uncle in Dublin that was a dentist. His father was George Warren Chandley, born 1861/62 ; he was married to Martha Susan McGuffey, whose father was James Thomas McGuffey and his father was James McGuffey born 1707.George Warren Chandley's father was John Myers Chandley born 1825, and his father William Chandley born 1802?.  Any help would be appreciated as we are going to Ireland in 2015 and would love to meet some cousins. Thank you
