Hi Walter, hope this helps, it's out of my memory, but I can check further when I get home tonight. Most creameries along the LHR were owned by Borden's in the 1920's. Hixon's and Maybrook, although at opposite ends of the railway, were owned by the same owner for a while but the name escapes me.
Great Meadows-Route 5, then later Route 6
Long Bridge (Allamuchy)- Long Bridge Road- owned by Mutual Milk and Cream
Allamuchy (proper)- Allamuchy/Johnsonburg Road
Tranquility-present day Route 611-owned by Borden's

there were milk stops/stands in Maple Grange (Vernon) and a few other points on the line but these were abandoned around 1905.
There were additional ice houses in Andover (Hancock's), Lake Iliff(Knickerbocker's), Lake Grinnel (Sparta), and White Lake (Sparta)
If you can get access to my book I have pictures and more info of most creameries.
