He was Allan Burton CHAPMAN b. 1864-5-6 somewhere in Summit County; that was before Summit vital stats like birth records began being kept in 1868. The earliest hardcopy we've found is his enrollment at Western Reserve Academy, which was then a college, 1879-1882.
He is shown on the 1880 census boarding in a SPRING/WARRINER household, as students did then. Whoever guessed his age on the census thought 17, but he can't have been over 15 with a Nov. 8 birthday. He was not on the 1870 Summit census in any CHAPMAN household that I have found. On censuses and other documents he states both parents born OH.
He spent most of the next several 3-4 decades in Canton, Stark County, with an assortment of 3 wives and families. He did not speak of his family, other than to say his father's name is/was John.
By about late 1880s-1890 he called himself an electrical engineer and wired up the whole house with electrict lights - one of the first if not THE first in Canton. This was while William McKinley had his law practice in Canton, before elected President of the U.S.
Two big clues. What CHAPMAN had the money to pay four years'tuition, books, room and board while he was a student at WRA? What CHAPMAN family passed on blood type AB?
