Wedding Photograph -1909

The above photograph appears to be a wedding photograph of my grandfather, Casimir Theodore Yehle and his bride Katherine Germing taken around the date of their wedding, 11 May 1909, in St. Joseph, Missouri. 

I cannot identify the two individuals on either side of the picture, maybe the best man and maid of honor (?) and maybe related. Any information on their identifies would be appreciated. .
