Andrea - I tried to reply directly to the email addresses given by Genforum for both you and Dan Masters. As frequently happens with addresses provided by them it failed to get through. So here is my message again:
Thank you both for replying to my message on Genforum. I have little to go on with regard to the Knipe I am looking for. My wife's gggrandparents were William Graham and Charlotte Knipe. They married in Calcutta, India in 1816. William was Headbook keeper to Palmer + Co who were one on the big trading houses in Bengal. Their 2 known children were born in Calcutta in 1820/1. All I have for Charlotte is her name on the record of their marriage. Charlotte's father's name was not given. She may have been born in India or she or she and William may have been born in UK. So if either of you have lost track of a Charlotte sometime just before 1816 I would be interested to hear.
