Hi Dissman
The Ashford PR transcript that I have (
http://www.genuki.org.uk/big/eng/DBY/ValNealCDs.html#Ashford) only has a few Bland entries as follows:
24/3/1689 baptism of William, son of Thomas & Grace Bland
8/12/1703 baptism of Sara, daughter of Thomas Bland junior
26/3/1716 burial of Grace, wife of Thomas Bland
27/1/1719 marriage of William Bland & Margaret Stone
9/5/1728 baptism of Margaret, daughter of John & Margaret Bland
6/4/1737 burial of Margaret, wife of William Bland
22/1/1738 burial of Margaret, wife of John Bland
14/5/1738 marriage of John Bland & Elizabeth Wragg
16/5/1742 burial of Elizabeth, daughter of John Bland
3/6/1743 baptism of John, son of John Bland
13/3/1752 burial of William Bland
26/1/1770 burial of John Bland
1/11/1772 baptism of Ann, illegitimate daughter of Elizabeth Bland
4/12/1803 burial of Elizabeth Bland, widow
It's just about feasible that Ann's mother was Elizabeth Wragg, if she were only a young girl at the time of her marriage and almost fifty when she had her, but more likely I think that John & Elizabeth (Wragg) had another daughter named Elizabeth after their earlier one died.
I'd be checking to see if John Bland left a will.
