I have a list of ancestors given to me with no info other than names and Birth and Death dates. The list includes John Hyder and four sons, three have the same names and initials as the Civil War soldiers who served in the 7th MD Infantry. The spelling of the names on my list are Hyder, the name on the Civil War Muster list show both spellings. I am looking for my line of Hyders (Hiders) from Maryland.
