Rasin and Gustava came to NYC around 1906. We believe Gustava may have come first.

Josephine was a nurse and we believe a Lutherin Nun that made many trips to Madagasgar. We have a "family - census/farm" picture but unable to tell who or where it is.
Thanks in advance for any help. Jeffry Rasmussen
