Dear Joanne,
I don't have any knowledge of the Daughter and can't find anything in the basic searches. I wonder if she died as an infant? The BDM doesn't list her in Australia.
I don't have the name "Kennedy" in my notes either for George Percy so that is interesting.
I don't have the children of that marriage as yet, but I have been to the garden where he and his last wife's ashes are. (I do have both marriages)
I have access to the archives to be able to photograph some of the documents on this George Percy I have already looked through a few but...
At the time I had no idea he was related to the George Percy I was looking for.
I have some of the George Percy Snr's daughters marriages from the parish registers.
I found it amusing that they appeared to all like much older men

I will contact you as soon as I can access the PM system and hopefully share some info.
I have just aquired photo's of Norman etc.
Nice to meet a new Cousin!
Woodzy
