Hi Christine, I am working on gathering information from a living Costanzo in Trail, British Columbia. My Argia Vannelli of Italy married Giovanni Costanzo in Trail BC and they moved to Fernie and then back to Trail. Most of what I can tell the Costanzo in Fernie were related to Giovanni. The person I am waiting on to provide me with more of the tree is very slow at getting on this project. I will keep you in the loop once I hear back from the living Costanzo in Trail I am relying heavily on to help me.
