Hi Halina I would be interested to see how far back you have gone with the Filsells. I think Peter is grandson of Al who was Samuel's brother.
I have very fond memories of Williamstown when I was a kid. Some of the stories I have picked up since suggest that "Pop" and Al were a couple of characters in and around Williamstown but history is history!
I have not heard from Owen and Rosemary Filsell for quite a while but Rosemary was compiling a lot of the Filsell history also. I do know that my neice, Ann Marriott has the family bible in which is recorded a fair bit of the Filsell history (long time since I have actually sighted that book but it does exist)
If Peter wants to contact me I am more than happy to talk. I am the younger son of Howard (son of Samuel) and Thelma.
