2.3) William White (1617- aft 1684?) bap Hornchurch 13th May 1617 He was apprenticed at the age of 15 on 25th June 1632 by his mother Anne Drake to Richard Bury of Dorchester to learn the grocery trade (Apprentices had to be between the ages of 10 & 18 and he was bound to serve for 8 years). As a result he and his brother John became merchants there for a while before removing to London. He married Dorothy the daughter of Richard Bury and they had at least 6 children which are mentioned in his brother (James) Will in 1666 as being John, William, Ann, Dorothy, Josias and James. We know that his son Josias who would appear to have been the eldest was educated at Wadham Hall Oxford where he matriculated on 18th March 1663/4 at the age of 16 so he was born circa 1647. He is recorded as a Pauline exhibitioner 1663-7 and was awarded his BA 28th Jan 1667/8. William and his family suffered badly from the Great Fire of London loosing all their household goods. William was one of six executors to his brothers will, the others being advised to follow his advice, and there is speculation that he went to Boston to live following his brother James death in 1666 (26) but he was certainly in London when he proved the Will on 11 February 1668.

A younger son of the first John White, of Southwick, settled at Stubbington, near Titchfield, and it is possible that from him descended the Whites, who came from that neighbourhood to settle at Portsmouth shortly after the Restoration of Charles II. John White built a " Victualling House " called the " Antelope," in the High-street, in the year 1672, some remains of which still exist behind 19, High-street. He became Mayor in 1690, and his initials appear on the keystone of the arch above the west entrance of St. Thomas's Church. He died in 1698, leaving two sons. The younger was a Lieut.-Colonel in the Army, and died in 1756, but the elder son of John White was an Attorney at Portsmouth, and was Mayor four times between 1724 and his death in 1745. Thomas White, son of John, also served as Mayor in five different years between 1752 and 1774. He died in 1797, leaving an only son, the Rev. William White, Alderman of the Borough, who died in 1801. Mary White, daughter of James, and niece of John White, of the " Antelope," was mother of Alderman John Carter, who, with his sons and grandsons, filled the Mayor's office no less than 32 times. The last Mayor belonging to the White family was Sir Henry White, who was Mayor in 1813-4, and was knighted by the Prince Regent on the visit of the Allied Sovereigns to Portsmouth. He descended from William, a younger brother of John White, of the " Antelope."

Not descended from a younger brother of Edward White of Southwick but rather his father, John White of Southwick as stated in visitation of Hampshire.
