Married without anyone knowing

Hey all! So my fiance and I have decided to get married because he is extending his contract in the military and we have been doing long distance for the past three years and we are tired of it and want to be together. We talked about doing it in December last year but our whole family found out because it was posted in the paper and they completely ruined it for us and we ended up not going through with it. We want to try again this year but without them finding out. How do we do it without them finding out. We are in Pa and the last time it was posted in the paper without us even asking for it to be. So is there a way to avoid that
