Hi Arranroots, and Seren,
Thank you both for looking.
Arranroots, I think I will look into the death that Seren has mentioned, as even my mother didn't know that her grandfather had a brother called Thomas, and this is possibly why. Also, as his stepfather Evan Bassett was listed as dying in 1893 as well, maybe they had an accident together, or caught some illness together. If this is not the case, I hope I can come back and request further information.
Cheers
