I'm not related but in case Henk doesn't reply it's maybe nice to know that the parents of your grandmother are :
Gerrit Krösschell and Neeltje Dorst.
Gerrit , born 25-Aug-1876 Hillegom , son of Everhardus Krösschell and Anna Maria Vis.
He married 26-Sep-1901 Lisse ,
Neeltje Dorst , born 22-May-1880 Haarlemmermeer , daughter of Corstiaan Dorst and Jacoba Vlugt
Franscina is born 25-Nov-1910 Sassenheim
I think you still have relatives in The Netherlands because Franscina's brother Everhardus stayed in The Netherlands , got married and had at least 3 children.
I just found the website of Henk Krösschell : http://n.krosschell.ws/
