My grandfather was Acil Gleason and my ggrandfather was Orlando (possibly listed as Orland or Orlin) Gleason, born 11 June 1825 in CT and died 1907 in IA.He married Ellen Olds and he appears in 1850 PA census and ended up in IA.His father was listed as 'Nathan' - mother's name not listed.I am seeking any information regarding which Nathan Gleason (of the many listed in various censuses) was Orlando's father and who were, if any, Orlando's brothers and sisters.Orlando's children were Mary Francis (b. 1850), Acil (b. 1870), Edwin (or Edward), and Melvin (or Melville).Any information you may have regarding Orlando's father, Nathan, would be greatly appreciated. You may email me or post on the forum. Thank you very much for your efforts.
