I'm looking for the three children of Margaret BERK mentioned, but unnamed, in the will of her father, Henry Berk. Margaret m John Cargill in Sussex Co. 9 Dec 1847. She was deceased at the time of her fathers will in 1876. A Porter Cargill is listed in a census as a nephew of William Berk, Margaret's brother. Any help with these 3 children would be much appreciated. Thank you, Sharon Rhodes
