My dad was an avid golfer who made 2 "hole in ones" during his lifetime. One of these was made in the late 1930s at the Ingleside Golf Course. I found a cool map at the Bancroft Library UC Berkeley made in the 1920's showing the golf course which was located on what is now Parkmerced.
His first hole in one occurred where the Parkmerced Office is now located.
The map also showed 19th Avenue with a notation -- "M" streetcar to downtown.
