My dearest thanks to everyone who've helped me with this, all very gratefully received! So, I understand now that the Lloyd connection is from Elizabeth's maiden name before she was married twice, thank you!!
So, where does William Henry Lloyd fit in? He must be descended from a sibling of Elizabeth Lloyd, that assumedly married into my Edwards family, though the naming of him as "nephew" and "grandson" in the censuses doesn't altogether add up.
It's given me new areas for research though!
