Hi Iandj,
I stumbled on your post when looking for one of the countless James Glasgows. It's a tradition that still holds to this day with most of the males in my family being John or James.
Newton may refer to Kirknewton, as there are several Glasgows from there, the Newton name is also sprinkled through.
I don't have much for your particular search, but I have a lot of information on Kilwinning, Kilbirnie, etc. The four in Ayrshire were likely cousins who knew each other, with the others being more distant cousins
Paterson reports that Rev. John Glasgow, Minister of Kllbirnie from 1688 to 1721. "had fourteen children; but there is no tradition on any of them save his son" Dr Robert Glasgow of Puddockholm (aka the Waters) (bpt 17.10.1693, surgeon at Kilbirnie) m. (15.12.1726) Margaret Allan of Ladesyde
Dr Robert Glasgow had a brother James, shipwright in Irvine. Capt James Glasgow,
Irvine shipmaster, mentioned 1740, maybe burgess (ayrshirearchives). From “Decennial indexes to the services of heirs in Scotland 1700-1859”:
Johns grandfather 1583, Robert Glasgow also married a Jonet
Conynghame, Her family descended from the Earls of Glencairn.
Additionally I believe John Glassford of Dougalston and Whitehill (1715 – 27 August 1783) Scottish Tobacco Lord, (
https://en.wikipedia.org/wiki/John_Glassford) may be descended from Reverend Joh "Jonat" Glasford who appears as Minister of Kilbirnie, From 1614 to 1629.
His son 1671 James Glassford (
https://www.wikitree.com/wiki/Glasgow-1094), marries Margaret
Semple. who were closesly intertwined with the Spreulls (his presumed grandmother). Additionally on the birth records, the name switches from Glasgow to Glasford/Glasfoord/Glasforde.
There is also an Alexander Glasgow who marries a Agnes
Cunninghame in 1773. This pattern seems to be found in clusters with Sempill/Spreull, Dunlop, Kirkpatrick and various others; with these names also appearing as elders of that area; and record of several other graduates likely in positions for the church 1635 Archibaldus Glasgua M.A, 1690,Nathaniel Glasgow M.A.
Taking us back to 1394 William de Glasgu, priest, was gifted the abbot and convent of Kilwinning& Kelso in 1394, with John Glasgow and William Glasgow of Cavers, Roxburghsire parish notably surviving a shipwreck
Between 1200-1700 the Glasgow's appear to have been devoted covenanters presbyterians - following Calvinistic theology and Gameronian principles, with John Glasgow and William Glasgow of Cavers, Roxburghsire parish norrowly escaping their enslavement in the fatal shore wreck of the croune (10, Dec, 1679); leading to the lack of records for this period;
Much of the history obscured by the anti-Comyn writings of Scottish annalists such as John Fordun or literary historians such as Buchanan who, forgeries and even voluntary name changes such as William Glass (1786), Founder of the Remotest Community in the World. Born Kelso Born William Glasgow in Kelso. He set up the rules for the people living on Tristan da Cunha. They are still the basis of the Tristan da Cunha society of today. The council decides how to spend the communal money earned from the crayfish exports, and ensures that a member of the family with the lowest income gets the next job to come up. Everybody works for the common good. Everybody helps each other. Everything is shared; there is no private property.
