Daniel O'Day and his son, Daniel were both in Missouri at the time of their deaths. Chambersburg is a little spot (no town) in Clark County Missouri near the Iowa line. My grandmother has told me Daniel Sr immigrated from Ireland and spent time in Kentucky before being the first Irish settler/immigrant in Clark County.
Daniel's (Sr) wife is Mary. Last name has varied - my mother had researched and has "Kinney" as the maiden name. (Logical, as one of the sons has this also as a middle name) but someone on the computer has it listed as "Kearney". I have a note that Mary and Daniel were married in Clark County, Missouri but I have not yet ordered a copy of the marriage license. I need to as the date listed is after my gg grandfather's birth. I'm starting to wonder who John's mother really was.
Where are your "Daniel"s from? or their wives names? There is a marriage also listed for Clark County Missouri listing Daniel R. O'Day marrying Annie B. Murphy on Feb 20, 1893. klb
Lastly, there is a Daniel O'Day buried in Chambersburg with Adda b:4 Apr 1869 d: Aug 22, 1889 buried next to him.
