Margaret Ellen Shrader 1848-1926 and her son, Asa Lavata Van

I found this picture posted on the photo website Picasa in 2010 and the website has since been discontinued.  The photos were linked to the original owner, however the links no longer work.  The photo was labeled "Margaret Ellen Shrader 1848-1926 and her son, Asa Lavata Van ,  Margaret is the daughter of George Washington Shrader b-1816 and Mary Ferguson, & the sister of Andrew Edward Shrader b-1864."  I believe this Margaret is a sister to Dialtha Shrader Moon.
