Francis is the eldest child of Nathaniel Bowman and Anne/Hannah (unknown surname). He was baptised October 24, 1630, at St Dunstan and All Saints, Stepney, London, England. We might assume his parents were living nearby, and therefore that he was born in the region of the Stepney church.
Of course I can't mention the church at Stepney without reminding you all of the Oranges and Lemons bell-ringing song. Click link for more details.
Shortly after Francis was born, the family emigrated to the early Massachusetts colony, settling in Watertown, MA. All six of his siblings were born in Watertown, as have been described and detailed in the book by Henry Bond, Genealogies of the Families and Descendants of the Early Settlers of Watertown, Massachusetts. They were: Mary, b. abt 1633 (died young); Joanna, b. abt 1635 (died young); Dorcas, b. 1639, died 1639; Nathaniel b. 1641-1707 (did not marry); Joanna b. 1642, married, children; Dorcas, after 1643, married twice, children.
What I looked at in horror was the fact that by the time Francis was about 10 years old, he'd seen three sisters die as babies or toddlers. Wow. What must have that felt like-? I haven't done research to find out if there was an epidemic or an unusual event to have caused three deaths over several years. The next three siblings survived into adulthood.
On the 26th day of the 7th month 1661, in Watertown, at the age of 31 years, Frances married Martha SHERMAN; Martha was the daughter of John SHERMAN and Martha PALMER. Note that her name is spelled Marthy on the register.
