What stands out about Elsah Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
James Semple, a local lawyer, prominent politician and United States Senator from Illinois, founded Elsah in 1853 and offered free lots to anyone who built houses with stone from his quarry. It is believed that he named the village of Elsah after Ailsa Craig, the last outcropping his family saw as they departed Scotland for the United States. By 1861, the village had grown to its current size, as geographic and economic limitations prevented further expansion.
