I wonder if you're still active and will see this ... I believe that there might be a connection to Harrison's son, Peter and Loammi Brown. According to the record book of the Aledo Cemetery (Mercer Co., IL) a Peter Brown was buried in #1 of the Brown Plot. However once the records were updated to cards, Peter is no longer listed but Loammi Brown is. Loammi is my 2nd great uncle. Thanks so much!
