I have the book "Descendants of Johanes Gnage and John Kenege Sr. and Related Families" by Eugene E Kenaga.
Johanes Gnage was an immigrant to US in 1742. This book tracks the descendants of his six sons: Christian, John, Ulrich, Joshua, Jacob and Joseph.
Your Jeremiah Kenaga (md first to Mary Ann Houlton and then Rebecca K Houlton) appears on pg 80 as the son of Abraham Kenaga and Christina Susanna Seese, and then on page 86/87 with his two spouses and their children.
Perhaps you've already gotten the info from this book.
