Josephine Bagan and Edna Los were sisters and shared the same mothers and fathers.
As a young man, my family [frank & Valeria Jurczak] would visit the Bagan family who lived in Binghampton, NY.
Irene would have been closer to my sister Constance Jurczak Prusik who was born in 1935.
I'm not clear as to how the Bagan tree attaches to my Jurczak tree.
@roger e. jurczak I believe you are talking about Josephine Nycz MWMY-34V and Edna Nycz MWMY-3WG.
Your common ancestors are Joannes Nycz and Karolina Zygmunt. Josephine and Edna were sisters, which would make Irene Bagan and Valeria Los first cousins. Irene would be your first cousin once removed. To see this visually, go to Irene's page https://www.familysearch.org/tree/person/details/GHK6-KWX and click on the View Relationship under her ID number.
