In order to see the wills that are at the ERO you will need a subscription to SEAX or request a paper copy, fees are reasonable.
**I did find one entry in the ERO, SEAX catalogue index that will prove useful.
**They have a file ref T9 Spurgin: correspondence between Bradwell and Southminster families.
This may help tremendously, it is not digitized so I cannot read it you will have to request copies.
Hatfield Peveral
John Spurgin widow who married Mary Hurrell 1744 in Westminster is possibly the one who married Ann Hays 1727 by license from the Bishop of London.
They had John, Ann, John and Martha.
Possibly a father or uncle to those whose wills I found.
1) John Spurgin, Victullar who died 12 March 1803 and left a will as follows.
Wife Grace
daughters Ann Ling, Mary Livermore, Elizabeth Waltham, Martha Spurgin.
Executor brother William.
From the parish registers, he first married Mary/Marie Richardson 22 December 1755 by License
both were single.
After Mary/Marie died he married 2nd Grace Knight a widow of Little Waltham 7 October 1783.
His daughter Ann Margaret born 1757/8 married Owen Ling 28 April 1778
His daughter Mary married Benjamin Livermore 2 May 1795, witness Ann Margaret Ling
Both girls were minors and were married with consent of father John Spurgin.
William Spurgin whose will was written 23 October 1807 proved February 1809, farmer and salesman.
Wife Mary
sons William and John, daughters Martha, and Sarah Spurgin, Mary wife of James Green Caslake of White Horse Street Stepney and Ann wife of James Livermore.
Executors son William and son in law James Livermore.
Parish Registers
William Spurgin married Mary Hart by license 5 February 1776.
Daughter Mary Spurgin married James Green Caslake of St Mary Whitechapel 21 May 1798 by license. Witness her brother John and sister Martha and William Caslake.
Daughter Ann Spurgin married James Livermore of Little Baddow 1 October 1805 by license. Witness her sister Sarah Spurgin, William Spurgin (father or brother) and her cousin Mary Livermore who had married Benjamin Livermore.
This William may or may not be the brother of John above see below.
Also baptising children at Hatfield Peveral are John Spurgin and Elizabeth Harden both were widows and he is from South Weald so yet another Spurgin family.
The other is William George Spurgin 24 who married Mary Ling 23 of Stoke by Clare Suffolk about 1781. witness was Owen Ling.
The parish registers are careful to distinguish the children of William and Mary from that of William George and Mary.
So the Hatfield families are totally separate from the Bradwell /Steeple/ Tillingham/ Southminster families.
