I went to the health dept. a couple weeks ago in Georgetown for a certified copy of my mother's death certificate which was a recent death. The cost was $11.OO. I didn't notice how far they go back but I did see a sign that said genealogy re search was allowed on Thursday and regular copies were $1.50.
Before I went to the health dept. I had gone to the Probate Court. Again I don't know what year the records start. The Probate Court is located in the Old Courthouse on the Square. You are put through a search as you enter like at the airport.
Let me do the check at the local library for your marriage licenses and then we will see what we can do for the other. Eva
