Thank you “mowsehowse” for your input, it is much appreciated.
I have seen that information and I’m not sure some of it is correct. There is a lot of assumptions in the info, Thomas and Hannah only had 11 children, Henry being the last in 1833 when Thomas was approx. 64 years old, Thomas died at 81 years in May, 1851, this shows the last 2 children born in 1849 & 1851, 16 and 18 years after Henry and Thomas being 79 and 81 years old, the year of his death.
There are Family Trees that show William Thomas Cowan Williams and Mary Spurrell married in Westminster, there are trees that show William Thomas Cowan Williams showing he married Mary Wheller in Westminster, but very little info after that and no documentation to back-up any of the dates, only a marriage record that they married.
I’ve attached an article published in the Brecon & Radnor Express with details from my research, all backed by Welsh, English or Australian records and to the best of my ability with what is available electronically, I match dates and names backwards from my Great Grandfather.
Again, thank you very much for your help, if you are able to help with any other information, it will be much appreciated, Regards McFab
