Henry was my 5th Great Grandfather. I am descended via Lydia Last - Betsey Chenery - Eliza Ann Sheldrake - Florence May Bannister - then my Gran who is still with us.
I have had a look at your tree. There is a differences between the information you have on Henry and the info I have - but then again I could have missed some information as I have only had chance to go through the parish records once. I am at work at the moment, so will need to check what I have.
I do have a tree online which at the moment has very few dates - it's about time I updated it!! It should be on my profile as Archer Quarter (I think it is a public tree - let me know if you have any problems).
