Declan Toole is the brother of Gregory Toole. It is unclear if he is currently employed by the railroad.
Declan is a New York police officer who was born in Ireland. Gregory once spoke of a brother who lived in New York who lived in a building ten stories tall, though it is unclear if he meant Declan. ("The Lord's Day")
Declan arrived to find Eva and her baby. He cites tradition that a man should marry his brother's widow and care for her children as his own. Eva resists him, even after he offers to take her to New York as his wife. After Eva's baby disappears, Psalms assumed that Declan took the baby since he didn't get what he wanted by persuasion. Psalms and two of his men locked Declan in the pig car and interrogated him, beating Declan with his own billy club. Psalms even claimed that he would kill Declan to get the baby back. After Eva's baby was found safe and not in the possession of Declan or his men, Psalms let Declan go.
