These girls must be related to our Leaning Lady, being that the photo was also made by Freedle and they come from the Leaf Album. It is unknown what their relation was though. I believe this photo to be a First Holy Communion for the older girl and some other type of religious milestone for the younger girl. I freely admit I am limited in my knowledge of religious activities, so if you have a speculation please add in to the comments section!
Who Were They? 
At the time of this photo c. 1890, the Czech (and immigrants) were almost entirely Roman Catholic by “royal decree” of Franz Joseph I of Austria.
“The First Communion, or First Holy Communion, is a Catholic Church ceremony. It is the colloquial name for a person’s first reception of the Sacrament of the Holy Eucharist” and typically takes place at age seven or eight.
“Traditions surrounding First Communion usually include large family gatherings and parties to celebrate the event and special clothing is usually worn. The clothing is often white to symbolize purity. Girls often wear fancy dresses and a veil attached to a wreath of flowers or hair ornament. In other communities girls commonly wear dresses passed down to them from sisters or mothers, or even simply their school uniforms plus the veil and/or wreath.”
First Communion is a step toward “Confirmation” (which usually takes place in the teen years.)
I am unaware of any “rite” for younger girls but am no expert on the subject. :)
