Well, that could be confusing, I'll concede, but if "David's mother" were being used as an appositive, a semicolon should follow it: "We considered Miss Roberts for the roles of Marjorie, David's mother; and Louise."

So here's my question: is it now ok to use the semicolon followed by a "however" ? As in the following sentence:
I used to be quite good at grammar; however, it's been a while.
It was always okay. In fact, your example would be wrong WITHOUT the semicolon.
However doesn't connect the two clauses.
I'll use this example: "The first part was easy; however, the second took hours." It looks like
however is connecting them, right? Suppose I rearrange it: "The first part was easy; the second, however, took hours." I haven't changed the meaning, but now
however clearly is not used to connect the clauses.

If you use the word however, however, you do not use the semicolon.
Just for extra clarity, I'm going to replace the first
however:
If you use the word dog, however, you do not use the semicolon.
This is a misleading example.
However appears to be connecting the clauses. If we remove "however", the real conjunction becomes clear:
If you use the word dog, you do not use the semicolon.
If is what connects these clauses, and a comma is needed because the subordinate clause is first. In reveal's original quote,
however serves the same purpose as in my example above ("The first part was easy; the second, however, took hours.").
Do you see the difference?
If you are using
however to mean "by contrast" or "nevertheless", punctuate the sentence exactly as you would if
however were not in the sentence. Then add
however in and surround it with commas. (It's pretty obvious, but if a semicolon's already there, you don't need a comma on that side.)
On the other hand, if you're using
however to mean "in whatever way", "to whatever degree or extent", or "in what way", you probably shouldn't have a semicolon next to it: "It was very clever, however he did it." Note that a semicolon in this example would change the meaning quite a bit!
