Has anyone seen the Memorial at the entrance of Gordon Moore Park in Alton, Il? I'm looking for a list of the names that appear on it. I'm looking specifically for Joseph GASKILL/GASKELL who died in 1868 in a Mining accident. Can't find any information on my gggrandfather and only have this information from descendants. Have tried for a death certificate, but can't find any or any other information. If anyone has information on this subject would appreciate some suggestions. Thank you, Edna
