Mary, Thank you for your search. I'm assuming that Harriet Dodd Gustin is buried somewherein Pulaski Co. with her 3rd husband Daniel Harper. Interesting that you found the name Bertha Gustin. Bertha must have been a family name since my grandmother and mother were both named Bertha. My grandmother was Bertha Jane Gustin-Prunty born 1882-1973 in Springfield, MO and my mother Bertha Jane Prunty Young 1915-2007 in Jacksboro, TX.
Thanks again for your search.
