I did not see the message to which you refer but I am trying to track down my Grandmother, Rosie Roznovak's, parents. Her husband was Frank Sefcik the son of John Sefcik and his wife Rosie (Rosa) Sefcik nee Roznovak. She was the sister of your great grand father John. :) I suspect my grand parents were second cousins but I can not find her in any records before her marriage and her birth certificate was destroyed in a fire a long time ago. I have never heard of her having been called Fanny. There is another Rosie in the family for sure that was my grandfather's sister Rosa Sefcik. I would love to exchange information with you if I have any that can help you. If you have learned of another Rosie I would love to hear of that.
