Hi, I just found this message board. Apparently Koob is a relatively common name. My GrGrGrandfather Melchior Koob immigrated with his wife Elizabeth and their children in 1854. They came from Hessen-Darmstadt, Germany on the ship William Jarvis, departed from Antwerp, Belgium and arrived in NYC. He settled his family in Lorain County, Ohio where he died in 1890. He was a farmer and a Catholic. My line comes from his son, John, who remained in Ohio also. I would enjoy hearing from anyone who is connected to this line.
