My grandmother's mother came off of the orphan train from New York. All her mother left with Foundling Hospital when she dropped her off in 1905, was the name Loretta Rose Rosenfeld. All she ever found out is that she was of European descent.
Do the names Loretta or Rose sound familiar to the family that you are researching?
I know it is far fetched; butI have hit so many brick walls trying to find my grandmother's ancestors.
