Is your Great Grandfather David Edward Bell Calderwood, married Mary A Hamilton - your Grandfather being Grimms Noah Calderwood with Brothers Bixby and David Marion and Sister Dionysia ??? (With family names like that how come you finished up Peter) - Hope you agree with my sense of humour!!!! In Scotland childrens second christian names are often from family surnames - my mothers second name was her mothers surname) - This could help track down a connection. Did you visit the web site I suggested.Best RegardsDoug.
