I am looking for any info on Roskamps in Hannover in the 1840s. Specifically, one John H Roskamp who was born in Hannover on Dec 1, 1840. His father's name was also John and his mother's maiden name was Schultz. He was married in 1865 in Liverpool, England to a woman named Annie Heaton. He died in Jersey City, NJ on Jan 7, 1917. Any info would help.
