Thank you davecapps! I appreciate your help.
I've added the original obituary that I found. Since finding this new (to me) obituary, I am convinced that Sicily is the birth place for Mr. Presta. The type used to print the obituary looks odd and it might be due to scanning. Who knows at this point.
As mentioned, he is a man with many names. I still haven't found him on a passenger list arriving to Canada. Two sons were born in the US and the rest of his children were born in Canada. I don't believe that he married his Canadian wife in Canada because I cannot find a Marriage Certificate.
I've found a Border Crossing that states he was visiting a brother named William Presto in the US.
Some of his children are named "Presta", "Presto", "Prest" and "Press". He also goes from Carmine Presto to Camille Prest on his children's birth certificates.
He has many aliases: Carmino Presta, Carmen Presta, Camille Presta, Carmine Presto, Camille Press and Camille Prest.
I will keep on searching and hopefully one day the information I seek will be finally found.
Thanks again!
