I am looking for information to update the Koehn family record of Heinrich J Koehn who married Helena Siebert. Heinrich's father was Jacob Koehn and Heinrich had four brothers: jacob, peter, benjamin and bernhard. They also had a sister but she died before the emigration to america. The Koehn family record was last compiled and published in 1962 so there is quite a bit of catching up to do. Any information would be greatly appreciated.
