Frank is my Brother. You are correct the three Kamerik Families in MA, FL and CA are all related. There are three brothers who are all still alive. I believe Frank was or is your grandfather. There is another Kamerik family in Iowa that was started in 1845 by a Marinus Kamerik who came to this Country with his mother and stepfather. They also are now scattered all over the Country. Your great grandfather Harry, (Hendirk Gerrit Kamerik) Came to this Country in 1920. He arrived in NY City as a crewman on a ship from Holland. When the ship departed to return to Holland he was not on it. He Jumped ship. Joined the Coast Guard married my mother had five children and the rest is history. The name has not been changed but back in the 1500s it was spelled Camerijck and over the years has changed spelling several times to todays Kamerik.
