The missing link in your inquiries of Jeltje van der Horn is to my knowledge my grandmother, Alice Vander Horn Snoop. How the name Jeltje, which I thought was translated Jennie, became Alice I do not know. My grandmmother was born on 13/3/1873 the Netherlands, she died on 27/1/1945, Paramus NJ. She was the mother of 6 girls and her husband, Johannes Jacobus Franciscus Snoop (or Snoep) was born in Goes, Zeeland,the Netherlands on 30/9/1873 and died on 14/10/1916, Hackensack, NJ. Let me know if this helps.
