Henry III of England and earlier Union with Scotland

4.5 months is kind of borderline so I'll link this and ask my main question, what if Henry III and King Alexander of Scotland younger daughter Marjorie married? As the previous thread shows there were a lot of problems with suitable partners and so he married quite late, but he could have married pretty early if this proposal had come about.

She was several years older than him but still in her early-20s, maybe 23 or 24, by the time they would be married for a couple of years and capable of producing children. She didn't marry till 1231 in our time line, so while she produced no children she could have produced a couple at least with him.

Granted, this was a little down the line since she was something like his third daughter, but there were other marriage is being made with Scottish nobility at the time as part of a peace agreement and if things work a little differently maybe Henry could marry the second daughter if not the oldest.

If his oldest sister lives longer they only a few years and King Alexander dies, Henry the third's wife and eventually his son could claim the Scottish throne. Perhaps even his daughter although Henry would probably have to fight for this. Or, just marry her to a Scottish nobleman.

How viable would this be end how would it impact English history? Would there be a willing Act of Union in the 13th century, I presume with the name of Great Britain? While it would be over 400 years beforehand, the name Britain was still quite well known at that time so I think would still be what it would be called.
 
I think you mean King William. Alexander II was his son and Margaret's brother. And Margaret did have one child with Hubert de Burgh - Margaret de Burgh, b. 1227, d. 1237.

If such a union did go through, I think some thing might depend on which side was bargaining from a position of strength. Alexander II and his army marched as far south as Dover during the French invasion, which I'm sure is something Alexander won't be willing to let Henry forget.

Margaret was IOTL married in 1221, when Henry was still in his regency.

Basically, I'm not sure if it would lead to an earlier union, though it may have been possible, given that Alexander II only had one child from his two wives IOTL. Personally, I reckon a better chance would be for Margaret to marry Arthur of Brittany.

Personally, if Alexander II wants a marriage alliance with England, he'd go for him marrying one of Henry's sisters, which he did IOTL, and/or marrying Henry to either Isabel (b. 1195) or Marjorie (b. 1200. https://en.wikipedia.org/wiki/William_the_Lion#Marriage_and_issue)
 
Thanks, yes, I was getting Margaret and Marjorie mixed up but was thinking of Marjorie because she was born in 1200. I definitely got William and Alexander mixed up because as you say, Alexander is the one who marched South as far as Dover.
