The majority of the memorials I've added have a connection with Marion County, South Carolina. Permission is not needed to use anything I've posted to Find A Grave.
If someones obit, death certificate, etc. states they were born or died in Dillon County and it was before 1910, they were born or died in Marion County. I use this on the memorials I add, what others do is up to them.
Many men never used Sr. or Jr. as suffixes to their names, even though they were. If the suffix isn't added to their marker or mentioned in their obituary I generally won't add it.
"If the interred had more than one last name, they may be added to the last name field. Our search will search all names in the last name field."
"Put the entire first name (if known), even if the grave marker is only an initial. Put the entire middle name (if known), even if the grave marker is only an initial."
"Since the move to Ancestry and the new website, newspaper obituaries, death certificates and other scanned documentation is allowed. We encourage members to move the images down to the bottom of the photo display so that they are not the first thing you see when viewing a memorial page."
