My name is Maria Masztalerz (family name: Suplicka). My father Stefan Suplicki (born on December 15th, 1907) was a child of Walenty and Maria (his second wife). Walenty Suplicki had two children from the first marriage. Both of them came to USA before First World War. Walenty Suplicki was born in Russian annexation of Poland.
Please let me know if you are ancestor of Walenty Suplicki.
