Tweedie Family

I am researching the Tweedie family of Glasgow, specifically the descendants of Robert Tweedie (1882-1959) and Mary Barrass McMillan (1886-1963). Their children were George, Annie, Robert, David, Catherine, Alexander and Jeanie (there may be others). They lived in the Possilpark, Kelvin and Maryhill areas. Any help or information would be appreciated.
