Paying respects to my grandmother in Kykave & Radlice

I am traveling to the CR later this summer and hope to pay respects to the birthplace of my grandmother's parents and grandparents (as well as my grandfather's side).  My trip will focus on the places associated with my mom and grandparents' heritage.

In Kykave, CR: Jim Vaclav Urban (died 1932), father of Frances Urban Pliva, who was my great grandmother (who died of the Spanish flu in Nebraska in 1918), likely never knew that his granddaughters were sent to live with new families.  My grandmother, Martha Pliva Baburek, was raised by Augustin Foral and Anna Mary Baburek Foral.  Anna Mary Baburek Foral was the aunt of Martha's (non-biological but by adoption) cousin, Joseph Baburek.  Anna Mary Foral was from Babice 7, Brno Moravia Rakouska (7/19/82 to 3/10/71) and I will definitely want to visit this area and really would love to know if there are any living relatives.  Similarly, since Martha's mother died when she was 4, I'd like to pay respects not only to the place of Kykave, but also to Frances Urban's mother's hometown of Radlice, the Jindrichuv Hradec District (Volfirov village) in South Bohemia.  Her name was Marie Bartu (1873-1952) and she immigrated in 1880 from Radlice.  I wonder if there are any living relatives.  I will otherwise just walk around.  If there were people there, I am learning Czech just in case!  Any hints on the best beginning places to see if there might be a living relative with whom to possibly connect?
