I notice your question on the board.
Catherina de Dreu ( Kaatje ) arrived in the US in 1899 with her mother and sisters.
You can found this information on the webste of the American Family Immigration History Center.Ellis Island on-line.
I hope that this information is usefull for you.
Do you know anything about the sisters of Kaatje?And where did they lived in the US?
I hope to hear fom you,
Els van Wijk , the Netherlands
