Ah, thought I remembered your family! Here is a link to an earlier discussion:http://www.slaegtogdata.dk/forum/index.php/topic,52685.0.htm...
Carl Thorvald Hansen was born 10 July 1872 and confirmed 03 October 1886 (not 1888). SOURCE: Købelev churchbook 1859-1891, ops 20 #4
REGISTRATION in COPENHAGEN of INTENT TO EMIGRATE
Ann Jensen, kone (wife) age 30, destination NY City
with her is son Olaf Jensen age 1
Registration date: 03 March 1882
Last parish of residence: Købelev (on Lolland)
Last res. amt: Maribo [an amt is like a state in the USA]
(It is traditional Danish naming practice that she keeps her maiden name. Olaf Jensen is probably a mistake as he is Olaf Olsen)
So we'll look for the above Carl to immigrate after 03 October 1886 and see what his destination is.
