Kevin, My g,grandfather was Absolam Parker Robinson, who was married to Josephine Parks. A cousin has told me that his uncle believes Absolam had at least two brothers, the parents died young and the boys were split up and raised by different families. He believes there was an "Alex" with a son named "Alex". I am not sure if he meant Absolam had a brother Alex or an uncle named Alex. I have not found my Absolam's parents however in looking for Alex I did find in the 1860 U.S. Census, Missouri, Boone County, Perche Township, pg. 118, line 25, the following family:

Alex Robinson Age: 39 Occupation:Faarmer Born: K
Mary J. Age: 29
John W. Age: 9
Walter J. Age: appears to be 9
Thomas Age: 8
Alex M. Age: 10/12

I hope this is of some help to you.
