According the information supplied to me in "Descending Jacob's Ladder" from Debra Wake, Bertha Mahann was probably born in the mid-1880s in Texas County, MO. She married Isaac Cliborne Troutman, Jr. In the 1910 Federal Census, they were living in Craighead County, MO and had four children: (a) Frederick R(osce), born 1907c in OK; and (b) Roy A., born 1909c, in AR. Other family sources include (c)Roy, (d) Edna, and (e) Maxine in at later points in their lives.
Would love to share additional information on the Troutman side and learn more about the Mahans.
