Hi, Jaime. I responded to your other question, but have a feeling (a guess only, mind you) that it has been removed because it contained third-party DNA kit numbers. So some of this may sound odd out of context, but all the same...
For the time being, I recommend you put that yDNA haplogroup out of your mind completely. Until you have more information, it's only going to lead you down some false and time-consuming allies.
From what you've said, I'm confident that your J-M267 classification is a predicted outcome of your Y-37 STR test. J-M267 is the top-level SNP for the J1 subclade...estimates are that the marker arose between 4,000 and 24,000 years ago. Here's a quick Wikipedia read for some background.
FTDNA's predictive haplogroups are very accurate, as far as they go. What you can be assured of is that any male not in the J1 subclade is unrelated to your direct paternal line. But the haplogroup can serve no relevant function in matching other than that.
I would file those two kits with a genetic distance of 3 (of the 37 markers tested) in the back of my mind, but not spend any time trying to establish contact just yet. In very general terms, here is how FTDNA categorizes genetic distances for each panel of STR tests. Some markers are more volatile than others, and your TiP report should give you a better handle on the possible time to MRCA, but a GD of 3 at 37 markers puts it on the cusp of being only a "possible" from 7 to 15 generations ago." I also personally don't feel that upgrading to 67 markers will help you at this point. Upgrading will refine timeframe estimation, but won't find you any additional matches. What you really need is for a GD 1 match to pop-up.
I'm in agreement with everyone else that yDNA will mostly be a wait-and-watch for the time being. It doesn't sound like there are any solid leads to chase there yet, so I would be concentrating on autosomal DNA and starting to examine and map chromosomal segments on a kit-by-kit basis. And that very much includes those matches from your mother's side. They may not have much to tell you about your father, but their DNA might. The important thing now is to start to begin building triangulation groups. These eventually will allow you to identify which segments on which chromosomes you probably got from your mother, and which from your mother.
And good on ya for already reaching out to the cousin on the Facebook Group. Be happy to make contact with cousins on your mother's side of the family, even if they may not be able to directly help you with your goal. Be willing to share information that might help them, and make a new friend. :-)
By building data to form triangulation groups, you'll begin to have a confident idea of which matches are on your father's side. A GEDmatch Tier 1 "for fee" feature that might interest you is one called "Lazarus." With kit numbers from several cousins (the more the better, even 4th cousins) on your father's side of the family, you can create a new kit, a "pseudo-genome," that closely approximates your father's autosomal DNA...no yDNA, but still a handy tool for comparisons.
Good luck, and make sure your FTDNA preferences are set so that you're emailed when new yDNA matches show up!
