Johannes Bosma from Leens, Groningen, does seem like the best match from the emigrant records. Their children's names are Delia, Alice, Josie, Raymond, Alga/Allie?, Alberta, Jennie, and Catherine. They don't seem like Frisian names, so I don't think he is related to George Bosma. I'm not directly related, but am working on the different Bosma families to add them to my compilation of Dutch Immigrant Families of Northern New Jersey.
