The name has a very simple explanation, actually: they're Byron and Shelley's nicknames for each other.
See, Lord Byron and Percy Bysshe Shelley, the early-19th-century poets, were close friends. In the summer of 1816, they lived near each other in Switzerland along with Percy's beloved Mary Wollstonecraft (who later married Percy), Mary's half-sister Clair Clairmont, and Byron's physician Dr. John Polidori.
(It was during that summer in Geneva that Byron proposed that they each of them write a ghost story. Out of that friendly competition came Mary's classic novel -- and my favorite book in the whole entire world -- Frankenstein.)
In any case, "Albé" was Shelley's nickname for Byron. "Shiloh" was Byron's nickname for Shelley. Seeing as how I'm a die-hard fan of Romantic literature (it was my focus of study as an English major in college), it seemed a good choice for the name of the corporation that I formed when I struck out on my own.
Now don't you feel enlightened?
