sorry should have checked Isable's will where Philip is named (tho looks as tho the name partly overwritten) as son + heir - but heir to whom ? - if the land came via her then Philip would be heir tho Gilbt have a widower's right - after that if Philip + other 2 daus died without issue then would go to her brethren ie the Kegeens - Is John Skillicorn married to/descended from one of these;why also is Wm not named - if Gilbts 2nd wife was alive then why no mention
If purchased land then she could devise her half to whom she wished
