Lewis Goff Bramblett Family, Lebanon, IN

Looking for Ralph Bramblett family records. He resided in Tama, Iowa in 1965 and gave my grandmother extensive family groups of the Lewis Goff Bramblett 1824 KY married Mary Francis Troutman 1835 KY family. This family resided in Lebanon and Attica ,Indiana in 1800's. The line supposedly goes back to James Bramblett md. Millie Shrewsbury in War of Independence times VA. The research seems well-done as there are extensive family groups and birthdates, but my only documetation is Ralph Bramblett records, Tama, Iowa. Granny corresponded with him in 1960's.Any descendants or relatives of my cousin Ralph out there?
