Tara,
I was looking at the dates of the marriage certificates for Susan Eyre and Elizabeth Eyre. I think Susan Eyre might be a niece of Thomas, because supposedly (according to another poster) he had a brother named John, as well as his father being named John. She was married in 1900, so if she was 17 or 18 at the youngest when married, she would have been born around 1882/83, which makes her way too young to be Thomas' sister in my opinion.
But, it is possible that Elizabeth could be his sister or his niece. She was married in 1868, and if she was 17 or 18 at the youngest when married, she would have been born around 1850/51. Thomas was supposedly born in 1836, so if his father had a bunch of kids, she could be at the tail end. If Thomas' brother, John, is her father and he was supposedly born in 1835, he would have only been about 15/16 years old when she was born.
So, I think it's possible that Elizabeth was Thomas' younger sister, and Susan was his niece by brother John. But, just a guess. I have no way of knowing for sure, but the dates work out better for this scenario.
Or I could be completely off base and they are cousins of some sort...who knows!
Thanks for sharing these links!
Sincerely,
Jamie
