Frank McIntyre (January 5, 1865 – February 16, 1944) was an American military officer who served for many years as Chief of the Bureau of Insular Affairs, responsible for federal administration of the Philippines and Puerto Rico.

In the 13th century, they sailed from their ancestral home carrying a white cow, and settled on the mainland at Glen Noe by Ben Cruachan.

For many years, they paid the Campbells of Glenorchy a symbolic rent of a white calf and a snowball for their Glen Noe lands.

His brother and successor Captain Donald MacIntyre the fifth chief, tried but failed to make ends meet and the Glen Noe lands were lost two hundred years ago, in 1808.

Their son John Edward Dawson Lea (1859–1929) married Hannora McIntyre his cousin, who died on 10 October 1938.

Their ancient territory would seem to have been Tir Aeda (now the barony of Tirhigh) after the deaths of Rory O' Canannain and his son Niall O'Canannain in 1250, the sept declined greatly in power.

The site of the ancient seat of the O'Canannains was near Letterkenny the largest town of County Donegal, which is said on good authority to represent the hillside of the O'Cannons (English translation).

In a 1938 letter to his classmates at West Point, McIntyre reflected "I can never forget the unsolicited kindness of these professors at the University [of Alabama] to a young boy without influence and with not the slightest obligation on their part.

[1] McIntyre entered the United States army as a second lieutenant in the 19th Infantry, serving in various ranks until he attained that of brigadier-general in 1912.

McIntyre served as long-time Chief of the Bureau of Insular Affairs and played a significant role in the governance of the Philippines and Puerto Rico throughout this period.

At times, McIntyre had strained relations with other officials in Puerto Rico, such as U.S. District Judge and fellow Alabama native Peter J. Hamilton during the 1910s and Governor E. Mont Reily during the 1920s.

In his 2007 book Planting the American Flag: Twelve Men Who Expanded the United States Overseas, author Peter C. Stuart devoted an entire chapter to the career of Gen. McIntyre and his leadership of the Bureau of Insular Affairs.

The McIntyres were the parents of six children, who grew up primarily in Washington, DC: Frank Jr. James, Edward, Margaret, Marie, and Nora.

[1] James continued the military tradition established by his father and retired as a major general in the United States Air Force.

In large part due to his service as executive assistant to the chief of staff in World War I McIntyre's awards and decorations included the only French Legion of Honour, and he was invested as a Knight Commander of the Order of the Bath from Great Britain.

He also received the Army Distinguished Service Medal, the citation for which reads: The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Army Distinguished Service Medal to Major General Frank McIntyre, United States Army, for exceptionally meritorious and distinguished services to the Government of the United States, in a duty of great responsibility during World War I.

As Executive Assistant to the Chief of Staff, General McIntyre's breadth of view and sound judgment have contributed materially to the formulation and carrying out of policies essential to the operation of the military establishment.
