Hi, you may have made great progress since this was posted. Thomas Edward Williams was the brother of my grandfather. This thread certainly gives me a lot to go on! I may be able to help, Herbert Pryce Williams died in action in WW1, as far as I have found he didn't go to Canada. The other brothers were Thomas Edward, John Samuel, Joseph William, James Albert, Cadwaladr and Ernest. The three brothers who stayed in Canada were Thomas, John and Cadwaladr. Joseph and Ernest both went but came back. I'm not sure about James. There were also two sisters Annie and Hannah. If you are still looking and would like the records I can link to them for you.
