Super Max comment in regards to releigious preference influencing a side has been expressed in several books on the war and the native Nation tribes.
While most readers know that the Iroquois were not united and the Oneidas supported the patriots. The Tuscarora did as well.
ONEIDAS. Their firm support of the Patriot cause resulted in the breakup of the Iroquois Confederation. They were heavily influenced by Presbyterian ministers from Connecticut. They provided intelligence, scouts and even small warbands in support of the Patriot forces. Their towns became the target of Mohawk raids. After the war, they were forced to make land concessions despite their support of the Patriots.
TUSCARORAS. Originally from the Virginia area, they were forced north in the early 1700s. They were adopted into the Iroquois Confederation but were never viewed as a full member with equal rights. During the war, they supported the Patriot cause. Some warriors accompanied Patriot expeditions as scouts, but most of the warriors remained home to protect against attacks by Tory and Seneca/Mohawk raiding parties.
Other tribes supporting the patriots:
ABENAKI.. At Pennabscot, Maine an entire company was raised under the Massachusetts government for home defense. At Odanak, on the St Lawrence the village was divided with many serving with Patriot forces. The Patriot Cpt John Vincent's Company of Indian Rangers was composed of mainly Abenaki. However, some Abenaki served with the British at St Johns, Quebec and the Saratoga campaigns.
STOCKBRIDGE. By the 1770's several of the coastal tribes had been reduced to living in "reservations" near larger towns. The Stockbridge community included Wappinger, Housatonic and Mahican. They enlisted as a company and were often empoyed as light infantry.

DELAWARE (Aka Lenapes). A small coastal clan was located in New Jersey. The majority of the tribe had migrated earlier to the Ohio Valley. The coastal clan supported the Patriots and supplied scouts to various expeditions. One clan became known as the Moravian Delawares due to their conversion by that Christian sect. The Moravians advocated neutrality until the Gnadenhuetten Massacre in 1782. Chief White Eyes, Netawatwes, maintained a neutral or pro-Patriot position until he was murdered by the Patriots. Killbuck succeeded White eyes as chief of the pro-Patriot clans. The pro-Crown clans often joined warbands dominated by the Wyandots and Shawnee. As with the other Ohio Indians, the Delaware continued to fight the Americans in Kentucky for several years after the war.
POTAWATOMI, KICKAPOOS. The divisions in these Nations reflected a common choice among the Indians. Those tribes near the British base at Detroit were pro-British. Tribes like the Wisconsin and Illinois joined the Patriots and favored the Spanish and French agents after 1779. Though outside the scope of this article, it must be noted that Patriot incursion during the later 1780s caused these tribe to band against the Americans after the war ended.
