According to census 1921 for Lsteni it seems, Josef Sokol and Anna Havel had not children. They are not recorded in this census any children there.
Alzbeta Sokol born 15th Oct 1879 in Lsteni # 38. She married 24th Apr 1906 in Lsteni to Jakob Vlcek born 14th Sep 1878 in Krenovy # 35. They lived in Krenovy after wedding. I found their daughter Anna born 1st May 1907 in Krenovy. She married 11th Apr 1931 in Stankov to Josef Krejci born 18th Jun 1909 in Kvicovice # 77.
It can be possible Anna Vlcek had some siblings born in Krenovy. It is possible Josef Krejci and Anna Vlcek had some descendants born in Kvicovice. I know that some family Krejci still lives in Kvicovice there.
All the best.Tony.
