Has anyone found a link between the Caldwell family nd the Brisbane family (way back). The Caldwell's are much more numerous than the Brisbane's. They have a few things in common:
William Brisbane was Chancellor of Scotland in 1332.
William Caldwell was Chancellor 1350-52.
Both families are reputed to have come to Scotland in the train of the FitzAllans.
They occupied areas close to each other.
A Sir Adam Mure granted land to a Thomas Caldwell of Todriggs at Kempisland in 1496 this was held until 1610 and eventually passed to the Brisbanes. I thnk that the Brisbanes may have also acquired Todriggs about a similar time.
The Brisbanes originally were located at Bishopston near Erskine on the Clyde River in Renfrew. They later acquired property at Largs and this was enlarged with the Caldwell land. They became the Lords of Largs and disposed of the Bishopston property.
The Brisbane family produced an early governor of Australia and lent their name to several places in Australia most notably Brisbane the captal of the state of Queensland.
The Brisbane's the Mure's and the Caldwell's were obviously moving in the orbit of the Stewart family in the mid-1300's - two Chancellor's and a Chamberlain. It seems logical that this had been going on for at least 200 years at the time (since the FitzAllan's first presence in Scotland) and here is evidence of business ties (if not loyalty or kin) going through to at least the mid-1600's.
This is a period of 500 years. One would think that something would show up.
I might also be confusing Bishopston with Bishoptoun - the latter might be the original holding of the Brisbane's - if so I don't know where it is. Further - the Brisbane's adopted their name after settling at Kelsoland - now Brisbane Mains in Noddesdale and taking their name from that property. What they were called before this I do not know.

Musings:
I suppose it is a fact that there was a lot that was going on and that the recording process was slow and laborious. Only some official documents have been kept and the historians only have recorded "exciting" things. Families have a habit of throwing out deceased parents records and momentos with no regards to the frustrations of future generations of genealogists - then there are the dark secrets of the skeleton closet which only become respectable several generations later by which time the story has become embellished to bare recognition. I suppose if everyone had kept everything there would not be enough warehouse space. I just wish that there had been a bit of selective and intelligent culling - for posterities sake. The thrill of the chase is good but the frustations are almost as great.
