Yes, I’m still researching…..sounds better than chasing rabbits! Anyway, I just found further info on Isadore Levy.
I’m excited to find the name of the probable owner/seamstress, Isadore’s wife. Her name was Marie-Joseph Renie.
So, do I change the name of my dear FW? I think I’ll call her Izzy. She is well used and a practical gal.
Have a great day and look out for rabbit holes!

Holy Cow, Katy! What a wonderful history of your little FW! I’m a huge fan of [genealogical] research and I would have done the same digging you did. It was meant to be yours and I love the name Izzy.
How about calling her “Mary Jo”, to honor Isadore’s wife, the seamstress who used the Featherweight machine?
Wonderful story, Katy! I know a lot of people would not have taken the time to do the research you have…so glad you did!
