Would love to connect with people looking for Leenheer family, from Tholen, Zeeland. Many "Jacobs" and Leenderts" in this line. Jacob Leenheer and wife Johanna Marie Hermsen came to US in 1872, settled in Cook County Illinos. But can find no trace of their death, burial, etc. From 1880 to 1900 there is no trace of them, then their Illinois born children start showing up in the census. Also, would love any recommendations on good books or sources for Zeeland history.
