Wonderful! So I just visited the other forum and they've already found out a lot. That's an amazing group of researchers.
Jens Marius Laurids Petersen born 13. aug. 1882 Ane Kathrine Andersen Sigaard born 1. jan. 1885
The forum found that Ane Kathrine immigrated in 1911, along with her children Martha age 6, Hans 5, and Agnes 11 months: Arrived 13 June 1911 on ship Hellig Olav from Copenhagen. Anna Pedersen 26. Last residence: Varde. Destination: J. Pedersen painter c/o Alfred Larsen, Jersey City, New Jersey. Nearest relative in place came from: mother Christiane Sigaard, Billum. Birthplace: Mollerup, Varde (the town of Varde is near Esbjerg).
In 1921 Ane K. Petersen visited Denmark with Agnes and Ellinor and returned from Copenhagen to Brooklyn (this was found on ellisisland.org)
Some of the researchers are from Denmark, some are from the USA. The forum is for non-Danish speaking folks - most of whom speak English.
