Gravestone says Abraham Long was 80 years old when he died. Possibly the father of Samuel Long because buried next to Samuel's daughter, Ruth Eliza Long, and one row from Samuel and his wife.
I'm sure by now you already have this information, but in case you didn't, I wanted to send this on to you.
Have a good day.
