Seeking information on or descendants of William Seabrook, born Essex, who married Mary Ann Du Feu (born 1854 St. Helier, Jersey) 1874 in London. William a gardner, and Mary Ann returned to Jersey. They had at least 8 children including William, Edward, Agnes, Edith and Amy. After the death of their unmarried daughter, Amy, William & Mary cared for Amy's young son, Frederick. We have been unable to find the date of death or burial place of Amy although we believe she died about 1912 in London. Any help would be much appreciated. Thank you.
