I am a Knowlden from the Kent area, Tunbridge Wells to be exact. Around 1800 when your family moved to the London area, there were some Knowldens who moved to the states, Pennsylvania, USA. Our family has taken measures to preserve our British heritage, including preserving as much information as we can. I am currently trying to learn more about our family from England. Let me know if there is any information I may be able to help you with.
