I am targeting a 2:37 marathon in Boston this April. (6:00 pace). I am also registered for a half marathon in January, 13 weeks out from
Boston. I won’t be super fit at that point, at least not specific race fitness. My question is, what half marathon time would be a good performance indicating, with 13 additional weeks of miles, a 2:37 marathon?
1:15 to 1:16
I take that back. Probably like 1:20?

There's no way anyone can answer that question without knowing you as an athlete.
1:18 or better.
If you want to race it, then I'd say 1:15-1:16
If you want to be a little more conservative, run the first half at 6:00 pace, then maybe 5:45-5:50 for the second half, which would give you more like 1:17.
Personally, I think it is good to practice racing so I'd opt for the former.
Really tough to say. I ran Boston 2017 and ran 2:34. I was coming off of injuries and ran a half while I was still rounding back into shape in early December 2016 and ran 1:14:5x. I then ran a half (Houston) about a month later after a getting a good stretch of workouts under my belt and ran 1:11:0X. My fitness tends to improve quickly, so that was not shocking to me. My goal was maybe to break 2:30 at Boston if I got good weather (the weather was not good, so I ended up running slower than I hoped).
So, putting that into perspective for you and applying it to your facts - I was racing a half at about my goal marathon pace about 4.5 months from Boston and was racing at a pace that predicts out well for my goal pace about 3 months out when I ran Houston.
An extreme anecdote to illustrate the "it depends" principle: I ran a flat-out 1:19, and 6 weeks later I ran a 2:30.
