Allreds in the American Revolution
To our knowledge, all of the American Allred families were living in or near Randolph County, NC during the Revolutionary War. Several of the men were American Patriots. Some served in the Militia, others provided goods or services to the American Cause. Two filed Pension Applications which are full of details. For the rest, we have found Military Pay Vouchers and listings in the North Carolina Treasurer's and Comptroller's Accounts.
Some of the Allred men are clearly identified on the documents. But, because there were several men / boys named William, Thomas, and John, it's hard to sort them all out or have definitive proof of which man is listed in each document. In most cases, all we can do is make an educated guess based on our knowledge of our family genealogy and the ages of the Allred men during the war years.
Per the 1779 Randolph County, NC, Tax List, and other records, the following Allred men were "of age" to serve in the American Revolution:
Thomas Allred - born 1771. He was once thought to be the son of Thomas Allred and many still refer to him as Thomas Jr. but more recent research, including family letters, lead me to believe he was the son of Solomon Allred (died 1782 Richmond County, NC). Thomas would have been old enough to participate during the final years of the war. (Documentation shows some boys as young as 12 years participated in the American Revolution.)
Thomas Allred - (born about 1725 - died 1810) one of the "original" men who first came to North Carolina in the 1750's
Elias Allred - (1757-about 1840) son of Thomas Allred (died 1810), estimated to be 21 years old in 1779
William Allred - (1755-1827) son of Thomas Allred, estimated to be 29 years old in 1779
James Allred - (1756-1847) son of Thomas Allred, estimated to be about 34 years old in 1779
John Allred - (born about 1725 - died 1792) son of Samuel Finley and an unnamed daughter of Solomon Allred (born 1680 England). He was one of the "original" men who first came to North Carolina in the 1750's
John Allred - (1759-about 1810) son of John, 30 years old in 1779
William Allred (c1715-c1781) son of Solomon born 1680, owned land in Maryland before coming to North Carolina
William Allred - (c1730-1825) son of the elder William (c1715-c1771)
William Allred - (1765-1849) grandson of the elder William (c1715-1771) , was 14 years old in 1779
John Allred - (1764-1849) grandson of the elder William - 15 years old in 1779
A William Aldred is listed in a document dated October 1781 titled "Men Over the Age in Dobbs County, NC" on file in the NC Archives. This caught our eye and needs to be mentioned here although a study of the original document shows he was an Aldridge, not Allred. However, since the abstract and transcription of the record says Aldred, I included him here.

Volume I
Elias Allred is listed in Volume I, page 95, folio 4. This volume report Special Certificates which were used by the holders to pay state fees for land entries made during the 1783-1784 in what later became Tennessee. These certificates could be (and often were) sold for cash. Special Certificates were given in exchange for services provided to the Continental Army and/or American Cause. Services could include providing supplies, food, shelter, ammunition, information, etc. These men may not have been actual soldiers or members of the militia, but did provide support to the American effort in some way, qualifying them as American Patriots.
