Luis Martinez, Minerva or Guillermina, St. Louis (MO)

[pipomiguel]

Hi!
First of all, sorry about my english
Mi mother's uncle was Luis Martinez Zimmermann. He was born in Arnao (Asturias) and migrated into the U.S via Cuba. I guess it was 1910-1920.
He lived in St. Louis, Missouri, and I'm pretty sure he had at least one daughter because my mother told me she came to Spain once.
I think her name was Minerva or Guillermina, because she was named after Luis' sister but I don't know which of both.
Thank you very much, and congratulations on this amazing website.
Best regards
Miguel
