Not to be confused with Caldwell, Coldwell or Couldwell, the multiplicity of these names should have an apostrophe before the 's'. Commonly we see Coldwells when referring to Coldwell families - the distinction should be made by using Coldwell's so as not to confuse us who are Coldwells'!
My full name is Albert Brian Coldwells, born in 1940 in England and emigrated to Canada in 1943. i find the search for my relatives on Ancestry is complicated by this common misuse of the manner of reference to multiple families.
