Hi Judy
When I triple checked the SFHG database for Northiam burials I did find the 1820 death for William after all, so it was either operator failure (more likely) or an inconsistent data retrieval search programming error. More likely it was me, but I will watch and see if any other instances.
Its interesting to note that our young William Attree (1794) was the one we thought may have been the William Attree death in 1796 in Brede. If they are related, he would have been the grandson of the Westfield William Attree (1705) with the elder dying possibly in 1786 also in Brede (Recorded burial in Brede William Attree 5 January 1786). I am wondering if William the younger was named for his Grandfather. Within the SFHG records William the younger was recorded both in the Attree name section and in the Tree section with each name as an alias to the other. Attree was also recorded in both instances (Grandfather and Grandson) as both birth and burial names.
I think I found other instances of the Attree alias, but I will double check. It may have just been William the younger that I wrote in a couple of places.
Another thing that I noticed, the other William who was buried in 1820 of Beckley was likely to have relocated there from Northiam to live with or near his oldest son Henry. Henry has records of two children born in Beckley, Thomas 1805 and Martha 1812 with wife Elizabeth. Henry was born in Northiam to William and Martha.
It could be possible that Cranbrook William may be the Grandfather instead of Westfield William Attree also, if it was a second family. I am leaning towards Westfield William though as the Attree name and location of the Grandson pulls the strands closer. Will dig some more around this and see if I can find anything further on either William.
I didn't come across any other baptisms at all for Daniel's children, or other marriages in England. I only found the Maryann Celia one in Kent, same as you. He definitely does not have a marriage listed in the Sussex database. I also had a good look to see if I could find any baptisms for Griffess/Griffiths but no luck there either. I did find his marriage record though.
Now, getting back to the Attree link, and a fun little side track I went down... I did just a generic Google search on 'Attree name origin'. The more boring explanation was something like 'He lives at the Tree', but an alternative and more interesting explanation was that it was actually derived from the old English 'atta reid' (from the clearing) or atta rie (from the river bank... or something similar). It turns out the town name of Rye is also derived from rie, or the (river) bank. Given the close proximity of our locations to Rye, I am thinking the name Attree (whether our or not) quite literally means At Rye, or Of Rye. The earliest recorded instance of the name was for John ate Reghe of Sussex in 1287. So, even if not relevant for our family I still found it quite interesting.
Another thing I noticed is the male line tends to live well into their 80's. Its a healthy lot (if they survive infancy).
