Spent hours looking through libs assed and vast today.
Lib Assed
1712 Wm Kewley was entered for Kerroo Dhoo Alia Begoade for 9s 4d part of 30s
1722-25 as above together with new intack no 64 for 3s entered 1725
1750 Dan Kewley entered for 9s 4d [Wm's son]
Wm died 1740 but intack no 64 was still in his name in 1750
1783 Dan Kewley entered for both Kerroo Dhoo and intack 64 9s 4d and 3s
By 1797 Alia Begoade 9s 4d is in the name of Wm Cain together with intack 64 [o1812 is mentioned]
1838 Wm Kewley Kerroo Dhoo + intack 64
1870 Wm Kewley heir of John Kewley [brother I think] 9s 4d and 3s.

Lib Vast
1760 Slegaby Intacks Wm Kewley / Daniel Kewley his son 3s
The father is dead and the son entered as right heir according to a composition for that purpose

So how can it be that Isabel sold what I presume must have been intack 64 @ 3s to her son Stephen in 1758 [although the deed is dated 1769] when it seems that her older son Daniel is entered for same ?

Is there anywhere else I could be looking please?
