The Iowa Marriage Records as seen at familysearch.org shows this marriage record:
Andrew J. Rogers m. Carrie L. Bort, 9 October 1893 in Delaware Co. IA.
His father is shown as Roswell Rogers, his mother as Elizabeth Holcomb. Carrie’s father is shown as E. W. Bort, her mother as Sarah Matheson.
But there was an earlier marriage for Andrew J. Rogers.
Andrew J. Rogers, b. 1861 PA, married Minnie Pike, 13 April 1885, in Linn Co. IA His father is shown as Ransel Rogers, his mother as Betsy E. Holcomb.
I found one Iowa birth record. A female child was born 21 Sep 1887 in Linn Co. to Andy J. Rogers and Minnie A. Pike Rogers. This would have been Letha.
According to the 1900 Delaware Co. IA census records, Opal Rogers was born July 1890. So both Letha and Opal would have been from the first marriage of Andrew J. Rogers.
Apparently both Andrew J. and Carrie had died before 1910, although I have not been able to find death records.
