1857- Asa is born in Illinois although his parents had lived in Missouri a couple of times. By this date they had gone to Indiana where they remained until the Civil War broke out and moved back again to Missouri.

1881- By this year Asa had moved back with his family to Clinton Co., Indiana where he apparently meets and marries Mary Willis Henry. The marriage certificate states that they were married in Thornton, which is just across the southwestern border of Clinton Co. but in Boone Co., Indiana. We suspect that it may have been closer to go here than to the Clinton county seat.
 

The fact the S. L. Henry and Ida Henry were witnesses to this marriage give us reason to believe that the Mary Henry is related to the Henry family of Kentucky where Squire Sturgeon has been found. We still have not discovered proof that positively makes this connection.
