Edward Wheaton, keeper from 1934 to 1946, made a gravestone at Point Betsie to honor his mother, Martha Madsen Wheaton, who lived from 1857 to 1941. She died in Cheboygan, but because he could not lift the gravestone into his car to take it there, he left it on the grounds as a memorial to her. Martha Madsen Wheaton had come as an immigrant from Norway, married the lumberjack Andrew Richie Wheaton, and lived in the Upper Peninsula. After her husband's death, she raised their six children by doing house cleaning in Cheboygan.
