Erastus Darwin Halladay (b. 4/12/1852 / d. 9/23/1908) and his wife Henrietta Teresa Gaines(b. 3/15/1867 / d. 6/27/1950), were my Great Grandparents on my mothers side. Carlos Darwin Halladay and Roxina Sheldon were his parents. I have quite a bit of info on them including some pictures. Let me know what you need and I can send them to you in Family Tree format.
