Believed to be the Asa Darby family

This photo was sent to me by Betty Orton.  She is a descendant of Mary Ann Darby, a sister of John Wesley Darby, my third great grandfather.  Betty and I met through DNA matching on MyHeritage.  She is my fourth cousin, once removed.  

Mary Ann Darby's family settled in Cloud County Kansas.  Asa Darby's family settled in Washington County Kansas, which is next to Cloud County.  Betty wasn't sure which Darby family this is but I am confident, based on the ages of the children, that this is Asa Darby and his children.  It seems to me that this photo was probably taken in the 1905-1910 time frame.
