I have been researching a Lanvermeyer family--Hermann Lanvermeyer who settled in Dearborn County, IN. He is shown on the passenger list with your Lanvermeyer family. There are two males in the group whose ages seem to indicate they could be brothers. One is Heinrich Lanvermeyer who is listed as being 19 years and 8 months. The other is Hermann who is listed as being 20. Not twins but too close to be brothers. Do you have any information on Hermann?
