That should be Merritt Chesnut Alexander and he went by the name Chester. I found him living in Brooklyn in the 1900 NYC census. I also found he and his wife Hazel in the 1910 Census in NYC with Chester, Jr. who was born in ca. 1909.
Further, I found Elizabeth Lane Merritt in Fulton, CA in the 1910 census. Only her child Ariadne is listed as living in the household with her and relatives of her aunt, the McDougalds.
