Researching the ancestors and descendents of my third great grandfather Henry (Heinrich) Seebeck. He was born in Hannover, Germany about 1817. Departing from the port of Bremen, he emigrated to New York City, arriving in 1839. Somewhere between 1840 and 1845 he married Rebecca Grimm, also from Hannover, who arrived in New York City in 1840. Their children were born during the 1840s and 1850s. The 1860 US Census finds the family living on the west side of Manhattan. If you think there is any connection on either side, or that you have any additional info, please contact me. Thanks.
