Good find Bob - very exciting! (BTW I presume you meant Ferdinand's death record?)
Sandi, more about immigrants from Schleswig-Holstein here:http://www.rootdigger.de/Emi.htm
This area (the duchies of Schleswig and Holstein) was under Danish rule before 1864, then won by Prussia in a war in 1864, then northern Schleswig returned to Denmark ca 1920. The family stories of descendants of immigrants from this area often include some confusion about Denmark and Germany.
