Hi Dave
Unfortunatley all records of these Lodges/Chapters have now gone. The Order lost most of its records in the war. What is left is all over the place. You may find some records of individual lodges in local history collections.
What is most interesting to me is to collect bits of stories about Lodges I dont know. This is why your photo and the jewels are so interesting.
Yes the Order still survives but there are only about 11 lodges left in the Country although there are many more in Europe, USA, Australia etc. These belong to a sister order the United Ancient Order of Druids, a friendly society which broke away from the AOD in the 1830's.
The AOD are a bit like the masons or the RAOB in that they meet in Lodges and have ceremonies. They mainly have a social and charitable basis to them. The AOD can be described as the oldest of all the "modern" druid orders but like masonry there is no religious or political character to them.
The chapter jewels you show are Supreme Royal Arch medals. These show your ancester was both a member of his local chapter but also the national chapter. The chapter was side order to the normal AOD lodges (called the primitive lodge).
