How far can you trace back your military roots?

I'm a native American from the Kiowa Tribe. I was in the Marines 86-91 and Marine Reserves 98-99 and Army Reserves 00-01, my Grandfather Jack Poolaw was a Marine fought on Guadalcanal and other Pacific campaigns. His brother Pascal Cleatus Poolaw is the most Decorated Native American in U.S History Serving in the U.S. Army in WWII, Korea and was killed in Vietnam. He was inducted into the American Indian Hall of fame in Andarko Oklahoma. The U.S. Army named a Bldg after him POOLAW HALL, located on Ft. Sill in Lawton Oklahoma. My great grandfather served in the 7th calvary Troop L, which was a small unit of Kiowas, Comanches and Apaches during the late 1800's.

On my Dad's side he was the first to serve (Navy).
My Mom's Dad, Uncles, and brother all served. Grandfather and Uncle both retired from the USAF though Grandpa originally joined the Army Air Corps. A few Uncles were regular Army and the others were Air Corps. One Uncle won the Air Medal for air combat in WWII, flying a B17 (I believe).

My Mom also found evidence of a distant Uncle who served in the German Army during WWII.

Not continuously that is for sure but there are some Notables. Civil War Doctor and William Dawes that rode with Paul Revere.

Had a forebear who was a Captain in the Pope's Swiss Guard. After moving to N. America, one forebear teamster delivered cannon balls to Valley Forge.

I had an ancestor who served under Jean Lafitte when they supported the American Revolution by foregoing piracy and joining the US Navy. They were paid for their service with promises of land grants, those promises were filled with swamp land that is still worthless and unusable; my grandmother was the last in my line to own a piece of that swamp by inheritance.

I am the third generation in my immediate family to join the military. Had a grandfather that was in the Air Force, and both parents were in the Navy. I was born a Navy brat but decided that the Army would be better!

My father was 4-F (eyes and feet) and never made the draft. My Maternal grandfather served in WWII in Europe, He was in Signal Corp and ran wires behind the lines. My Paternal grandfather and both his brothers served in WWI in various places. My Uncle Austin sent home his helmet with a chunk of shrapnel still stuck in it.
Further back, Multiple Paternal great uncles and cousins were together in an Iowa Unit during the Civil War. Even Further back maternal many times removed great grandfather crossed the Delaware with Washington during the revolution. Grandpa (who served in WWII) did the research in case my sister or I wanted to join the DAR.

In the course of filling out my family tree over the last forty years, I have traced my military roots directly back to a number of grandfathers and uncles who fought in the War for Independence, the War of 1812, the War Between the States, World War One, World War Two, to myself in Vietnam. I have also discovered many European ancestors who fought for various British kings and other foreign monarchs during wars dating back many centuries. I am a direct descendent of Charlamagne, Henry III, and William of Orange.

On my mother's side, we go back to two sets of Patriots that fought in the American Revolution. Edwin Mardin/Marden who was a member of Roger's Rangers. Our familial homestead is on United States National Park Property, and played a role in several incidences during the Revolution. http://www.nps.gov/mima/hartwell-tavern.htm

Well let me see. I am Native American so that goes a ways back but paper wise I can say my Grandfather (Fathers side) was US Army Airforce P-61 Blackwidow, father was electronics tech USN then USAF (communications), step mother was USAF Xray tech (medical) then me.
Being Tuscarora and Onondaga mixed blood I am sure some members fought during the revolution days as well as civil war. Not sure on that end with the spread and history being lost.
