I am related to the Costanzo Family out of Fernie BC.
My grandfathers sister Argia Vannelli married Giovanni Costanzo in 1929/3/25 Trail BC. From here they moved to Fernie where I understand Giovanni's family lived.
Giovanni was born in the Region of Colosimi Italy. I have no dates of his birth YET but will research the marriage record I found of Argia and Giovanni at the library.
Giovanni's parents names were S.Gaspere Costanzo and Viola Gigliotti. I am not sure if they came to BC or not. I know Giovannai's brothers lived in Fernie but do not know their names. Many of the relatives to the Costanzo family live in Trail British Columbia.
Giovanni and Argia had two children a son named Cessar who lived in Chicago, and daughter named Jean who married into the Eddy or Edy family. Both are now deceased.
