Samuel McCoskry was born in Carlisle, Pennsylvania, on November 9, 1804, the son of Dr Samuel Allen McCoskry, a Physician, and Scottish-born Alison Nisbet.

He attended the United States Military Academy for two years, then graduated from Dickinson College in 1825; was ordained deacon and priest in 1833 in Christ Church, Reading, Pennsylvania.

McCrosky resigned in 1878, citing ill health, but allegations of moral misconduct came to light, and he fled to Europe.

The House of Bishops was unable to investigate McCoskry because of his absence, so it voted to depose him on the grounds of abandoning his diocese.

[1][2] Samuel Allen McCoskry was the 32nd bishop consecrated for the Episcopal Church.
