HELP WITH TOWN NAME NEEDED: LORTSTRAZA?

Dear Friends,

I have a naturalization document, dated 1853, from Boston, Massachusetts,which lists the birthplace of my immigrant ancestor (Henry C. Boeck) as "Lortstraza" or "Loetstraza", Denmark, in 1824.Does anyone on the list have access to an old Danish Gazeteer or Map which may give me a clue as to the location (or proper spelling) of this place name?Also - is the name "Boeck"a Danish name?If so - is the name common?I haven't done any research in Danish sources, and am a complete novice.Any help would be greatly appreciated.I would gladly exchange work in the Minnesota Historical Society for any information you can provide.Thank you very much.Best regards, Jim Sazevich, 454 N. Smith Ave., St. Paul, Minnesota, 55102-2726(651)222-8160.Email: [email protected] or [email protected].
