I am trying to remember where I got the information that Margaret was the wife of Job Donithorne.
Have decided to try working through some of the copies of Wills that I have available as that seems the most likely source.
In doing this I found another one for you at Towednack:-
JOHN HODGE, husbandman, of Towednack
written: 19 Sep 1638
proved: 20 Nov 1638
son: WILLIAM 10 sh now another 20 later
daughter: PRUDENCE w/o RICHARD EDWARD 10 sh
daughter: JANE w/o RICHARD DONITHORN 10 sh
daughter: CHESTON 6 sh 8 d
JOHN s/o WILLIAM HODGE 12 d
THOMASIN d/o RICHARD EDWARDS 1 ewe sheep
servant: BLANCHE 1 ewe lamb
wife: THOMASIN all the rest & executrix
witnesses: GEORGE NINES, RICHARD TAILOR, JAMES TREWHELA
Inventory taken 22 Sep 1638 by JOHN PARSONS & GEORGE NINES
AP/H/994
..........
So they had connections to Towednack also as early as 1638.
And then:-
ELIZABETH UPCOAT, of Zennor
written: 11 May 1678
proved: 22 July 1678
son: NICHOLAS BERYMAN 12 L featherbed, bolster, a pair of blankets, a pair of sheets, 1 coverlet, now lying in the middle chamber
MARGERY d/o NICHOLAS BERYMAN 1 brass pan of 5 gallons
daughter: JANE DONITHORNE 12 L & 1 chest

Elizabeth ( ) Upcote

..........
This connection goes back to a marriage at Gulval in 1632 between William Donithorne and Jane Berriman.
There are other Wills pertaining to Donithorne of Gulval but I will stick, for now, with anything relating to Zennor.
RICHARD BLIGHT of St. Erth, yeoman

her husband ALEXANDER TREMELLING 1 sh.

I am presuming this Job Donithorne was the son of the 'man in question' of your initial query.
If so then it means he was still living in 1760.

I have now been through the Wills abstracts from one source and am unable to find the reason for Margaret being the name of Job's wife.
I still have a lot more to work through but that will take some time.
As mentioned, I have largely left the Gulval connections out of this as there was no mention of Job or Margaret or any direct connection with Zennor.
There are some connections to Morvah but I will need to follow up on that later on.
The coupld of Towednack mentions should catch your eye but they could be connected with St Ives also.
I also have an abstract of the 1660's document for David Donithorne of St Ives whose brother was Dolphin.
Time to close for now and I will try and look more at the rest of what I have in the next day or so.
