According to capitan_kerryfugio, there were people named Merryman who were buried in Baltimore, proving that the corpses were neighbors and friends of Taney, and by extension, that made John Merryman a neighbor.
Merryman was in the cavalry and had a pony that was a lot like Lincoln, proving a family tie.
Taney was 46 years older than Merryman. The experienced Taney knew all the hot places to pick up babes, and he and Merryman hung out together.
The official record proves that Merryman was arrested at home in Cockeysville and transported by train to Baltimore.
In 1864, John Merryman fathered a male child, who died in infancy. The child's name was Roger Brooke Taney Merryman. Merryman must have been very grateful the Chief Justice wasn't able to spring him from jail.
