1) REf: I can't seem to figure out a family with Robert/Margaret Quine having both Robert Jr and John????

It was this Arderry family:

Robert Quine, of Onchan. Family lived at Ballafargher, then at Arderry from 1761.

Robert born 04 Sep 1716 , d 2 Mar 1789
married at Lonan 22 Nov 1744
Margaret Clague (of Ballavarrane Lonan) d 6 June 1779 Braddan
Couples three youngest children baptised Onchan
Robert b 18 January 1745 (married Jane Halsall of Patrick in 1778, Jane died d 22 Aug 1786, second wife Esther Kissack of Santon d 1793)
Judy b 19 August 1748
Margaret b 19 February 1752 married (?25 Nov 1788 Robert Lewn?)
John b 7 June 1761 died 1856 age 95 years Married 19 Mar 1796 Mary Quine of Ballig
Ann b 1 September 1765 married 26 Jun 1787 William Cowley
Thomas b 11 December 1768 married Mary Mason
Mary b c 1756 d 19 Feb 1805 Onchan, married Daniel Kewley

It was John of 1761 who had a son John that married the other Jane Callow that was mentioned earlier in this posting

2) The missing wife

John Quine b 19 Oct 1760 alive in 1841
married
?
children
John b 1788

A) John Quine md Margaret Clague 8 Apr 1780 Onchan
John ch 5 Nov 1786 Braddan

This John I think was from the Strenaby line, if I am correct he was born 27 Mar 1748

B) Margaret Quine als Clague of Arderry buried 7 Jun 1779

This was the wife of Robert of 1716

C) Thomas Quine married Patrick 12 Nov 1757 Catherine Quirk
Three births 1760, 1762, 1769 of children named John with a father Thomas possibly this couple.

Looked a possibility on the first one but I think based on the 1841 census it points to his father being named John and born c 1761.

This birth below looks a good possibility, but the mother is not named.

John Quine b 30 Sept 1781, Father John Quine [mention of Coilbee (Colby?) [Mother could it have been Isabel Cowil??]
