As I established on the L & M thread that John Jeffreys Denison Bowd b 1908 at Islington was the son of Herbert Bowd who in 1911 gave his age as 32 and his birthplace as Cambridge Town, I'll continue with the Bowds on this thread now we've moved to Cambs.
Herbert Edwin Bowd's birth was registered in the Dec quarter 1879 in Cambridge registration district, mother's maiden name PAIN.
In 1891 Herbert Edwin Bowd, 11 b Cambridge was living in St Andrew the Less, Cambridge with parents James 60 b Boxworth Cambs and Susan 54 b Swavesey, and siblings George 31 b Boxworth, James 24 b Swavesey, Arthur 22 b Brougham Herts, Charles 20 b Cambridge, Walter 17 b Cambridge and Ernest Alfred 14 b Cambridge.
In 1861 James Bowd 29 b Boxworth, Susan Bowd wife 24 b Swavesey and son George 1 b Boxworth were living in Boxworth.
There's a marriage in St Ives, Hunts, registration district which includes Swavesey between Susan Pain and James Bond which I suspect is an enumeration error for Bowd (it's a common error). You need to purchase the marriage certificate to confirm this, and to get James' father's name. This is vital as I hit a road block at this point. Censuses show a James Bowd or Boud b 1831 in Boxworth, son of William and Ann. But there's no baptism other than on 18 Dec 1831(which fits perfectly) in Boxworth son of John and Ann. Is the parish register in error? I suspect it is, but it needs the marriage entry to give father's name which I hope is William.
Get over this hurdle and I go back to John Bowd born c1685
