Many old newspapers from Delaware County are digitized and available here:
http://delawarecolib.newspaperarchive.com/Default.aspxAt that site I've been able to document/confirm all kinds of early golf courses in this county in southeastern PA that includes clubs like Aronimink, Rolling Green, and Merion.
Using the above site I got a lead on a series of articles from the summer of 1973 where the sports editor of the DelCo Times, Gene Gomalka, presented his version of the 18 best golf holes in the county (the first three are digitized at that library site, but the other 15 were obtained from microfilm). Most of these are fun reads, and the drawings at about my level of artistic ability.
I found it neat that he chose to present as the first in the series the 5th hole from Clayton Park, a little 1600 yard layout still in existence (and the only hole of the eighteen articles I've not played). I really thought that was a nice touch (the penultimate and ultimate holes covered in the series are both from Merion East, which you'll have to wait for!).
Here's the first in the series (sorry, but the blue slider bar is needed).
