Don't know if it has any connection to H.E., but the "History of the City of Toledo & Lucas Co., Ohio" (1888) lists a TenEyck family in the biography section: Stephen & Lois TenEyck, their daughter Isadora A. TenEyck Micham (her children- Alma L. & Guy Wilbur Micham), & their son Daniel E. TenEyck (his children- Stephen O. & Frank WIlliam). There is a separate biography for Daniel; it says he was an artesian well digger, and a drain tile manufacturer. Both biographies are in the Adams Twp. section.
