Thank you for the extra information. I contacted a few people on the other site who had Elizabeth and Thomas HEW on their trees to confirm the details. Nobody can confirm when and where Elizabeth HEW died, though. I've only done a brief search using her various names, I know she's not a direct ancestor, but with all those marriages I was curious about her.
There's even a (supposed, I've not confirmed it) photo of her, which makes her seem more real.
