Please consider adopting Jacob de Zwaan, born in the Netherlands in 1849, the son of Willem de Zwaan and Annesje Mol. He emigrated to the United States and settled in Ottawa County, Michigan, marrying Cornelia Katherine "Kate" Vandenberg. They had a large family, which also should be adopted.

Most of Jacob and Kate's children had large families, which I have referenced in their bios and most of which have sources on FamilySearch, so if you're looking for a project or some long-lost de Zwaans, you're in luck.
