If Dorothy died in 2009 aged 71, then that gives her a birthyear of around 1938. Irene d. 1946 age 12, birthyear then would be around 1934. Since there is no public 1940 census yet, this family appears to be too recent to find much info online for.
I do not find a "Muir" Travis in any database, nor do I find any Travis who married to a woman whosegiven name was Muir."Muir" is usually a surname.As to info on Arthur, without more info I couldn't place him on census (too many results)
The closest match I find to a Dorothy Garrett who died this year, born around 1938: B. dec 10 1937. d. Sept 8 2009, resided in Benton, Saline, AR, and SSN was issued in Arkansas. This, as you know,would be your Dorothy.I found her obit in the Benton Courier (searched through epodunk.com) Dorothy Jeanne Garrett Thursday, 10 September 2009
