Pleich

Hi.

I am new to this forum.
I am looking for information on a Mathew Pleich married to Angeline Pavalich, they had a son that came to Canada named Andrew Pleich (1906-1993) born in Yugoslavia (Croatia) married to Albina Levar (1920-2022). I know that Andrew was interred during WW1 possibly in Northern , Ontario, Canada.

Any help in expanding his family would be greatly appreciated.

Thank You
Daniel
