Hi there, thanks for the tip-off.
The Will was signed in March 1807 and proved 10th August 1807 and mentions the following.
Sons John (and his sons John, Thomas, George), Thomas and William (and his son John Tapp).
Daughters Mary (otherwise Polly Parkins), Ann Cursons, Agnes Stanbury and Mahala Stanbury.
John Stanbury m Mary Shear 1769 South Tawton with the following possible bps.
William 1770, John 1772, Ann 1775, Thomas 1777 (bur 1779), Aggy 1780 (bur 1783), Thomas 1782, Ann 1783 *, Agness 1785, Mahala 1787.
* There’s also a marriage for John Stanbury to Mary Powlesland 1783 South Tawton.
Daughter Mary Stanbury married John Perkins 1788 South Tawton.
Daughter Ann Stanbury married Francis Curson 1794 South Tawton.
In post 39 above, Francis Stanbury bp 1804 Hatherleigh names his father as John, a serge maker - but this is unlikely to be John who made the Will - Francis would have been three years old and surely provided for in the Will. The question, then, is whether the son of John who made the Will, also called John (and who married Grace Lang) is the father of Francis.
By the time the Will was made in 1807, John Stanbury and Grace Lang had the following children: William, John, Grace, Thomas, Mary, James, Francis and Henry. The Will mentions John, Thomas and George - so perhaps John whose father made the Will is not the same John who married Grace Lang.
