I can't offer much concrete information about Meyer and Minnie, but his will (dated 14 August 1883) sure left a lot of clues. Here are some excerpts:

Meyer believed his estate was valued at about $21,000.
He died 11 May 1885. An obituary from 18 May 1885 Morning Journal-Courier (New Haven, Connecticut):
Death of a Macon Merchant.The Atlanta Constitution announces the death May 11 of M. G. Schwed, a prominent wholesale grocer of Macon, Georgia, aged thirty-six years...His firm were erecting a large and handsome business house in Macon. Deceased was a brother of Marcus Schwed, of this city, and formerly lived here.
I also found mention -- more than once -- in the local newspaper of the Macon Masons honoring the wishes of Mr. Schwed. Here's a clipping from the 11 May 1901 Macon Telegraph -- published sixteen years after his death (which incorrectly stated it was celebrating his birth).
THE M. G. SCHWED MEMORIAL TONIGHTThe Masons of Macon Will Enjoy the Feast Provided for in the Will of the Deceased Member of the Macon Lodge.The Masons of Macon will tonight celebrate the anniversary of the birth of M. G. Schwed, the story of whose will has been annually told in these columns since his death. He provided that a certain sum of money should be invested by Macon lodge, and the proceeds from the investment should be used each year for making merry on the anniversary of his birth. The Masons find it very easy to carry out his wishes in the matter, and tonight they will gather at the asylum of Macon lodge and do as the will directs.
Minnie, beloved wife of M. G. Schwed, died 16 April 1879 at age 26.
