Would like maiden name of Emma M I Ladwig, husband Herman F Wilhelm Ladwig of Hamburg, Germany born 1854. Both were said to have immigrated to New York in 1881. Would like to confirm Emma's immigration date since she is not listed on ship manifest with Herman. Children were born in Milwaukee Ward 17, Wisconsin beginning Nov 1881, etc. Looks like she made a visit to Germany in 1902 by herself. Also would like marriage date / place. Thanks for your help.
