I found a census record with a listing of my great grandfather, Phillip L. Davidson (born 1873 in Cuyahoga, Ohio). It lists his father as being born in the Isle of Man, but I don't know anything else about him. Are there any Davidsons in the Isle of Man who might know of an immigrant to the US in the mid 1800's? (Phillip married Emma Prysi in 1910 in Ohio.)
