I am very interested in any information that you have about this family.I have read some of the accounts of the slave life in Jamaica that are on Google Books. I have also being trying to uncover any copies of portraits but this has been without success.Lydia Foster Barham who lives in Uruguay has most of the portraits.I did email her but without success. I would love to correspond with you and discuss our common family history. Looking forward to hearing from you,kind regards, Susan
