Hi Lindsay
I don't know which bits you have already so I am going to try and put what I found yesterday in a logical order, it might be a bit long winded - please bear with me.
I have copies of the register transcripts for Bampton (OFHS) and at the period we are looking at they are quite good at distiguishing which families came from which hamlet that makes up the parish of Bampton. I found the baptisms of James (1796) Edmond (1798) and George Jones (1803) all children of John & Mary Cripps of Lew, there are some earlier baptisms of children of John & Mary of Aston but I think this is a different couple. I found Mary still alive in the 1851 census living in Aston with son George Jones Cripps she was born abt 1767 in Langford.
Marriage from Langford 28th Dec 1795 John Cripps wid (x) to Mary Jones (sp) witnessed by James Jones & Edmund Cripps
In the Bampton registers a marriage 1786 15th Sept
John Cripps of Lew to Elizabeth Johnson of Bladon
witnessed Soloman Clarke & Edmond Cripps
Baptisms for 3 children of John & Elizabeth Cripps of Lew Susanna 1789, Martha in 1791 & John 1793
Burials in 1794 Elizabeth Cripps of Lew age 26 and Susanna Crips of Lew age 5.
There are several trees online for this family but most seem to have mixed them up.
I looked to find Johns burial - Mary seems to be a widow in 1841 as well, the most likely one was in 1837 for a John Crpps of Aston aged 83 - that would give a year of birth of abt 1754 however I couldn't see a baptism for a John Crip(p)s in the baptism registers of Bampton at that sort of time.
