"Four children, three sons and one daughter, have been born to Mr. and Mrs. Duncombe, but only one of them is living, their son Charles McMillan.  From the age at which he entered school until the present time, his education has been carefully looked after.  He completed the eighth grade of the elementary and grammar school at Hamilton, passed one year at the high school in Decatur, and was graduated from the Hartford high school in the class of 1910.  At this time (1911) he is a student in the school of Professor Ferris in Big Rapids, which is considered one of the best of the kind in the state, and there he is pursuing a course in the commercial and business department to fit himself to follow in the footsteps of his father, his uncle and his grandfather as a merchant.
