To any interested persons,
Today, I "googled" Caydzien, which i've done occasionally
for the last few years.
For the first time in a while, a few new sites appeared.
Including, Dublin Census 1911 - George Caydzien and two daughters - (sisters of the two brothers - John and George who emigrated to Canada)
Additionally, an Enthusiast called Linton Love has already replied regarding a Family Site -
www.moyer-meyer-genealogy.com which appears to possible mention the son of either John or George - "Bruce George Caydzien".
Bruce had a daughter Beverly, born 1947 with Jacqueline Honsberger.
Could that be the same person who served in WW2 in the Royal Canadian Air Force - "George B Caydzien"
The mystery continues.
