Company Names, addresses, dates¹:
  Ivy Dale Farm Dairy - Rice & Stoneburner, Ballston VA (c.1908)

Notes:
An article in the October 1st 1908 edition of the Washington Times newspaper announced that the Ivy Dale Dairy Co was going to "start their wagons October 1, 1908", and that "Mr G.H. Rice would give his own personal attention to soliciting & delivering the milk". It went on to say that the cost was 8 cents per quart¹.

The 1900 census lists Thomas H. Stoneburner, b. 1866 in Virginia, as a farmer living in the Arlington District of Alexandria County. That district would have included Ballston, so he may be the Stoneburner referred to on the bottle below.

The Washington Post newspaper listed ads for boarders at the IVYDALE DAIRY FARM between July 5 1910 and July 11, 1911. They mention "Mrs. G.H. Rice" - so maybe Mrs. Rice was taking on boarders while Mr. Rice ran the dairy, or maybe Mr. Rice had passed away by then. The address on the last ad was "Route 4, Station A, Box 183".
The earlier ad says "Ballston" and later one says "Lacy". There is a sign on Fairfax Drive near Glebe Road in the Ballston area that describes the "Lacey Car Barn" that was associated with the railroad in that area circa 1910. A 1900 map of the Ballston area also shows lots that were owned by people with the last name "Lacey", so it's possible that area was also referred to as "Lacey" or "Lacy".
