Ok here goes this is what we have so far ... so I'm working with 2 other families ... mine is pretty simple with the discovery of Mary Mayo - although no baptisim found at this point but good assumption based in her grandsons name Frederick Mayo Wade.   I've made notes where the other two families descend from.  So I hope this helps makes sense

Totty Mayo abt 1749 - 1807 (this was notes for Totty - Also, there was a baptism record for a Totty Mayo in the index of the baptisms but the actual page (no. 7) was missing (pages 1-7 missing)  so I could not see any details for him but feel sure he was another sibling of Mary Mayo's, baptised before John Mayo in 1749.Also, there was a baptism record for a Totty Mayo in the index of the baptisms but the actual page (no. 7) was missing (pages 1-7 missing)  so I could not see any details for him but feel sure he was another sibling of Mary Mayo's, baptised before John Mayo in 1749.)
