I know Antonia was born to John & Mary Jirak on 12 Sept 1883 in Kutna Hora, Czechslovakia. She emigrated to the US before 1902. She married Joseph Richter before 1902 and they had two children Camille b. 1902 and Joseph Rudolph b. 25 May 1904. The family resided in Queens on the 1920 Census and I know for certain they later moved to Islip on Long Island.
I would like to find out if Antonia came with any family and who they might be. She could have family in Chicago but I have not found anything concrete to support that. She may also have two sisters, one possibly married a Baldwin and the other a Brown.
