Back with an update...
I feel like I was floundering around there and not really getting much progress. The best thing I did was reread this thread. Most of the answers I'm seeking were already addressed earlier.
It comes down (as first mentioned by Neale I believe):
It appears that there are two brothers John and William Dalgarno near New Deer and each of them is having kids around 1750/1760's . People on ancestry have come to believe that William & John are the same person but I don't think it's the case. Both were married to someone named Margaret Sangster.
It was John Dalgarno having a son named James in 1757 at Clochan with Margaret Sangster., witness John Sangster
Meanwhile William Dalgarden has son James in 1759 at Little Auchloch with witness George Sangster. It doesn't say wife was Margaret Sangster but it seems implied.
To the best of my knowledge James Dalgarno 1757 from John is the same one who is the weaver of Blackhills mentioned on the grave:
https://www.findagrave.com/memorial/232471280/james_dalgarnoI believe:
JD 1757 first married Margaret Gall and then Jane Taylor in 1788
JD 1759 married Margaret Ramsay 1781 and then possible Helen Hay in 1801 (no clues on this marriage doc)
So that's where it stands... I'm trying to find definitive prove that William and John are two different people, likely brothers that each had a son named James. If the documents are correct James Dalgarno who married Margaret Ramsay should be a blacksmith.
On SP the two are listed side by side and it looks like they are two different people:

I believe this James 1759 from the same William is the father of JD 1787 and married Margaret Ramsay (and possibly later to a Hay). So he would be cousin to JD 1757 the weaver of Blackhill.

Above: William is at Little Auchioch New Deer and John is at Clochan Old Deer.
It all hinges on whether James Dalgarno 1759 was a blacksmith at Earlseat Cruden ...
Forfarian already mentioned a bunch of this earlier and I'm thankful!
I feel like I have already received a bunch of help on this... but if anyone has any insights I'd be greatly appreciative! Anyone who has any opinions, comments , critiques... please feel free to chime in!
