There are two William Gill Lezayre Epis wills on BL's index at the right time for them to be missing from the 1841 census:
GILL, William 1822 Lezayre E 2 0106423
GILL, William 1823 Lezayre E 1 0106423

They could be the same will, or attachments which got separated from the first entry during filming. Or could be Williams snr and jnr, although Rhonda's information does look as though she has the correct family. She would need to look at both wills (on same film) unless an error in the index?
