Jacobsen
I am trying to locate a Jacobsen from The Nehterlands that died in the middle to late 30's and was a chemist in Amsterdam.I am the g-g-g-grandaughter of Elsie Christina Jacobsen who married Herrmann Christian Friedichse in about 1852 in Denmark.She was born in 1828 in Norbye, Schleswig-Holstein, Denmark and died about 1900.The Jacobsen I am looking for may be a brother to Elsie.Herrmann and Elsie's daughter was Magdalena Sophia Carolina Friedrichsen born February 26, 1853 in Barkelsby, Schleswig-Holstein, Denmark.She married Detlef Christoff Petersen November 13, 1874 and died June 15, 1939 in Reinbeck, Grundy Co., Iowa.She was my great-grandmother.If anyone has any information please reply.Thank you.
