Not in any formal way Tom, but I can't imagine they didn't know each other well.
Meehan was already one of the most prominent architectural landscapers in the country before 1910 (as was his father), had started his own club and designed the holes in 1909 (Edge Hill CC, which later became North Hills), and was named along with Crump, Carr, Smith, et.al. by Robert Lesley in 1915 to a committee assigned to creating the first public golf course in Philadelphia.
He was also seemingly friends with Wilson and Ab Smith, as they helped him with some significant redesign work at North Hills, and I believe Flynn was also involved, although I forget the details. You might ask Wayne.
