Fogarty and Crowleys

I only know the four on the right, Mamie and Nellie Fogarty and in front are two of their first cousins (Their mothers' brother's girls) Annie and Mary Jane Crowley. I suspect the others may be cousins as well, but unknown. I am hoping someone may recognize the picture and shed some light on this treasure, taken in the 1900's at Creve Couer Lake, Saint Louis County.
