The only son of Audrey Gardner (died 1588) and Sir Edmund Verney (died 1600), Francis Verney was born in 1584 at
Pendley Manor in
Tring, Hertfordshire, England. His father's first and third marriages into two other royal families, given the complexities of family ties in
Tudor England, made Francis one of an indeterminate number of stepchildren within the Redmaynes, Turvilles, and St. Barbe families; he was related to a total of seven royal families through marriage. Within
his immediate family, he had a younger half-brother, Edmund (1590–1642), who was born on 1 January 1590, the only child produced by Edmund and Lady Mary Blakeney. In 1599, Francis was married to his stepsister, Ursula St. Barbe, daughter of William St. Barbe of Broadlands and Mary Blackeney. The marriage was presumably arranged by Edmund and Lady Mary, described as a "masterful" woman, to cement their families fortunes and, more specifically, to protect the interests of Lady Mary and her daughter. She also persuaded her husband to divide the property granted to Francis by his uncle's will with their son Edmund. This resulted in the original will being superseded and this new settlement confirmed by a private
act of Parliament, ''''
(39 Eliz. 1. c. 10'' ). These moves greatly increased the influence and power of Lady Mary. Edmund Verney died on 11 January 1600, when Francis was only 15 years old, and was subsequently sent off to
Trinity College, Oxford in September of that year. Though little of his childhood is recorded, according to the
Dictionary of National Biography, he had "all the advantages that a fine face and figure, great personal courage, and a magnificent taste in dress could bestow". It was during this period that he began running huge debts spending as much as £3,000 a year. Leaving Oxford, Verney soon rebelled against his arranged marriage living separately from his wife in
St. Dunstan's-in-the-West (a
notorious neighbourhood of
Alsatia, where one of his servants, Richard Gygges, was murdered in a drunken brawl in 1604); he would legally separate from Ursula upon reaching adulthood and provided her £50 a year for the rest of her life. Verney was
knighted at the
Tower of London on 14 March 1603/4. ==Break with the Verney family==
