Good morning
I've had a look at this and I think Elizabeth Resen with the illegitimate daughter was your Elizabeth's niece.
Firstly it looks like John was still alive in 1713.
Elizabeth d of John Lea of Rowington was buried 22.7.1713 at Lapworth .Strange wording if he had already died.
Then their son Henry looks like he was buried at Lapworth
Henry Lea of Rowington buried 23.11.1722 .No mention of parents either because John had died or because Henry was and adult.
Secondly their is an Elizabeth Reasen bapt 15.10.1690 at Lapwoth d of Josiah and his wife gap written in faintly Eliza Resen . I think that is her and she went on to marry at Claverdon Sam Tompson 18.12.1712.
While I can't spot a baptism c 1660-1676 for your Elizabeth ,there seems to be one family at Claverdon.
Thomas Resen bapt 5.12.1631 son of Robert ,married Lucy Hargrave 10.19.1655
Children Maria /Mary 11.6.1654 married John Loe Clavendon 22.6.1673 by licence
Job 23.11.1657 who married Mary Weaver 20.5.1694 and was buried 25.5.1717
Children Josiah 19.11.1695,John 6.9.1696-7.9.1696 (apparently gravestone survives)
,Thomas 1.11.1697-18.12.1721,Josiah 22.3.1706-28.3.1707 Elizabeth 25.7.1711-6.11.1725
Josiah 29.5.1663 who married Anne Phillips 24.4.1687 She died 5.2.1723 and him
24.11.1729
Children at Lapworth,Calverdon and Rowington
Thomas 25.1.1688 ,Elizabeth 15.10.1690 Lapworth with Eliz?,Josiah 18.2.1693 Row ,Anne
21.5.1696 Row, Job 18.6.1701 Row, William 20.6.1703 Row ,John 30.12.1706 Rowington.
So it would fit nicely if Elizabeth was their sister and d of Thomas and Lucy .Somewhere in the gap of baptisms in the parish records 1666-1670 .
Thomas is on the Heath Tax returns 1663 1 1670 and 1672 4 hearths 1674 1
There is a Will for him at SOA apparently
Probate of the will of Thomas Reason of Claverdon, yeoman, whereby he devised his estate at Lapworth (which he had purchased from William Southerne and Barbara his wife) to his wife Lucy for her life if she so long remained a widow, and if she should remarry then he devised to his said wife out of the said estate at Lapworth a yearly rent charge of £5 for her life payable by the testator's son, Job Reason; and he devised to his said wife his messuage and lands in Yarningale in the parish of Claverdon for her life and, after her death, to his son Josiah; and he bequeathed to his wife £14 and one feather bed, bolster, pillows, hilling, blankets, two pairs of the best sheets, curtains, valances, bedstead and all other furniture thereto belonging; and he bequeathed to his daughter Elizabeth, £160 and one feather bed etc., and to his son Josiah and his wife 5 shillings apiece, to their children Thomas and Elizabeth 10 shillings apiece, and to his son-in-law, John Lowe, and every of his children, 12 pence apiece; and all the residue of his real and personal estate to his said son Job and his heirs for ever.
Witnesses: William Parker, John Cox and Anne Parker.
Proved at Worcester 19 October 1672 by Job Reason.
Grant of administration of the goods and chattels of Thomas Reason, not administered by Job Reason, to John Reason, great-grandson and only next of kin of Thomas Reason, 6 May 1780.
Job is a yeoman on a 1704 juror list.
No sign of John Lea over at Rowington .
The only Leas of Rowington I can see 1600s (besides what you have)
Mary d of William and Margaret of Rowington buried Lapworth 19.6.1689
John buried Rowington 8.10.1673.
But the Resens seem to hang together.
what do you think?
