We don’t know a great deal about Jan, the father of Wacław Jagiełłowicz, who is at the center of this genealogy. He was one of three sons of Jozef Jagiełłowicz and Anna Nefowna. He was born in Wiedzogała (Vandziogala) in 1863. He was the oldest of three brothers. His brothers were Anupras, born in 1864, and Eustachius, born in 1866.
We know that he originally married Barbara Montville (Montvilius) in 1885. His mother Anna died that same year. With Barbara, he had four children – Antoni, Wacław, Veronika, and Appolonia. We don’t have the date of Barbara’s death, but believe she died in approximately 1895.
Jan then married Anna Iwaszkiewicz and had many children:
1898 Valerian
Władysław
Benedict
1909 Ksavery (Xavier)
Kazimierz (Casimir)
Felicijan
Teresa
Aleksandra
Sofia
The above were all confirmed in correspondence with Felicijan Jagiełłowicz before he passed away. Other documents also refer to another son Piotr (Peter).
Jan remained active in the lives of his children. After losing his oldest son Antoni to the Czar’s service (never heard from him again), he encouraged Wacław to escape, which he did successfully. When Lithuania established its independence after World War I, Wacław helped Jan purchase a farm, where the family lived. Wacław visited his family during that period of independence. Reportedly Jan advised Wacław to return to the United States and raise his family there, which proved to be sage advice. Wacław remained in touch with his siblings, particularly Felicijan and Appolonia, throughout his life. Later, his children and grandchildren remained in contact with them.
Jan died in 1927, and is buried alongside his second wife, Anna, in Vadaktai.
