A commemorative Isle of Man stamp issued in 1975 honors 150 years of Manx settlement in America with a picture of the Clague Museum and Robert and Margaret Clague.
The Clague family tree shows the Manx national symbol as prepared by the Family History Center in Westlake for the Clague Museum.
The Isle of Man, circled in red, is located in the Irish Sea between England, Ireland, Scotland and Wales.
