"Ham” of the Bible is Noah’s son, and this fact eventually found it’s way into restaurant slang. “Noah’s boy” became an order of boiled ham. ”Noah’s boy, with Murphy carrying a wreath Ham, potato, and cabbage” was cited in print in 1932.
Diner slang of this type became rare after 1960, and “Noah’s boy” is mostly of historical interest today.
Wikipedia: Ham (son of Noah)
Ham (Hebrew: חָם, Modern H̱am, Tiberian Ḥām; Greek Χαμ, Kham; Arabic: حام, Ḥām, “hot” or “burnt"), according to the Table of Nations in the Book of Genesis, was a son of Noah and the father of Cush, Mizraim, Phut and Canaan.

“H. C.” OR “COMBO”
The ham and cheese sandwich, consisting of a slice of each, on rye or white, is such a familiar lunch wagon order that it has two pet names—“H. C.” from the initials, and “Combo,” an abbreviation of Combination Sandwich. In the same lively lingo of the short order, ham is “a slice of squeal,” ham sandwich, “a pig between sheets,” or “dress a pig,” ham sandwich with onion, “pig with a breath,” or just “Trilby.” Ham and eggs, “toast two on a slice of squeal,” ham, potatoes and cabbage, “Noah’s boy with Murphy carrying a wreath.” The Biblical name “Noah’s boy” for ham, suggests the classic “Adam and Eve on a raft and wreck ‘em,” for scrambled eggs on toast. And a ham sandwich to be wrapped up for eating off the premises is “dress a pig to take a walk.”
