Thank you Frances!

That certainly eliminates one major element of the structure!

Concerning the entry in 1740 Lezayre Abbeylands:
...."Wm Carret Broundell and Ann his daughter & Ewan Curlet her husband (o1746) 3s
Wm Garret 3s"

1) different spellings? - different person?
2) If same person, wouldn't there be a similar notification of change [(o1746)] in the entry for "Wm Garrett 3s"?
