Elizabeth, I have talked with a good number of Mexican Waldo's... not a one knew their grandfathers or where they came to have the last name.. It has been a long standing joke passed through our family.. my grandfather built 2 gigantic Glass manufacturing plants for the Mexican Government in 1933-1939. When I was in Reynosa I noticed a lot of mexican chaps that looked like me???? My grandfather was a widow at that time and very handsome, one never knows! I wish I could help you, but I never could get a line going in Mexico.. Victor Waldo e jo habla espanol..
