The Civil War veterans of the 27th Maine (with their honored guests and family) held an annual reunion on the 27th of August (unless it fell on a Sunday), beginning in 1882. This recent purchase brought to light the fact that Company C, which had been raised in Buxton and Hollis, also held their own reunions.

Their first meeting was held on Saturday, Jan. 14th, 1893, at the Knights of Pythias Hall in Buxton Center, where a permanent organization was formed. Captain Joseph F. Warren was elected President, Henry A. Chadbourne, Vice-Pres., James M. Hopkinson, Secretary, and John Martin, treasurer. 17 former members of the Company were present during the afternoon business meeting.
[see write-up in the Biddeford Weekly Journal, Jan. 20, 1893, pg 2] 

The above postcard was addressed to "B A Dow" of Standish Maine. The postmark is smudged, but was in Sept. 1899, and would have been for the seventh annual reunion. This man, Benjamin Ayer Dow, was not a 27th Maine veteran, but belonged to the 17th Maine Infantry, and apparently was an invited guest.

The Biddeford Weekly Journal, at times, would mention these reunions in their Buxton notes. They were still active in 1907, when a meeting was written about in the Sept. 20th issue of the newspaper. It was noted that, out of 100 men in Company C, 30 were left, and 11 were present at the annual reunion.

On December 9th, 1862, John H. Came wrote home to his sister, Miss Eliza C. Came, of West Buxton, Maine. He was a 1st Lieut. in Company C, 27th Maine. He died while serving in this regiment, on 16 Jan 1863, from typhoid fever. His body was returned home, and buried in the family cemetery in Buxton. He didn't marry.

Above is an 1861 map of Washington and Alexandria. Lieut Came wrote from Camp Seward, which was located somewhere along Arlington Heights. Bailey's Crossroads and Munson's Hill, where Co. C had done picket duty, is highlighted to the left of map. Camp Casey, where Lt Came would pass away in Jan 1863, was located south of Fairfax Seminary, northwest of Alexandria. Camp Vermont, where the regiment had spent the latter part of December '62, was just south of red arrow marked at bottom of map.

NOTES:

Sister Eliza C Came, daughter of Abraham L and Annis (Green) Came, was born 1833 in Buxton. She never married, and died in 1885. She is buried in the Came family cemetery. 
Page 2
"Warren" is referring to Joseph F Warren, also of Co C, who was 2nd Lt. at the time of this letter writing. Following John Came's death, he became 1st Lt (and later captain, when John Hill was promoted to major).

"Sam Davis" - I believe this is Samuel L Davis of Standish, Maine, who was captain of Co K, 25th Maine Infantry. He was "discharged for incompetency" on Dec 8th 1862 [according to ME archives index card].
There is also has some newer writing along the top that erroneously listed John's death as "Dec 16th", instead of Jan 16th.

​Frank C Came, of Co B, the fellow from York, was indeed Charles Came's son. I haven't trace their ancestry to see if or how closely related they may have been.
