Ambejejus Lake – Keith A. Beaupain, 73, passed away May 14, 2026, at Maine Medical Center in Portland, Maine after a period of declining health. He faced his final procedure with characteristic good spirits, and he slipped away peacefully, without suffering.

Keith was born April 14, 1953, in Lincoln, the fifth of eight children of Henry and Philis (Barnett) Beaupain. Keith grew up in Millinocket, graduated from Stearns High School, class of 1971, and like many of his generation, he went to work at Great Northern Paper Company in it’s heyday. He worked as a machine tender at Great Northern Paper Company until the Millinocket mill closed in 2008 and continued to work at the East Millinocket Mill until it closed.

For many years Keith also worked alongside his brother, Charles, doing home appraisals. He was a lifetime member of the Millinocket Elks Lodge #1521 and the National Rifle Association. Keith enjoyed hunting, fishing, playing cards, doing the daily crossword, and spending time at his house on Ambajejus Lake and his camp on Seboomook Lake.

Keith was a devoted family man who remained home with his mother following his father’s untimely death. He is survived by his siblings, Candace Hume, Dean Beaupain and wife, Elaine, Dr. Jil Beaupain, Kim Peters and husband, John, John “Jocko” Beaupain and wife, Judy; sister-in-law, Judy Beaupain; as well as many nieces, nephews, cousins, and friends. He was predeceased by his parents, brothers, David and Charles; sister-in-law, Silvia Beaupain; and brother-in-law, Robert Hume.
