It is this Broido associated with my search. I found information about it online ancestry. com: Jacob Broida Birth 1857 in Eishyshok, Salcininkai, Lithuania Death 1932 in United States, in 1910 has Residence: St Louis Ward 4, Missouri. His wife's name was Anna and they had nine children.
In 1923, in St Louis arrived grandson Jacob Broida, Nachum Krainovich. I guess that Nachum was the son of one of the daughters of Jacob, who was married to Efim Kreinovich, violinist from Warsaw.
