Using a search feature to mine information from old newspapers can be a lot of fun and reward you with information you never thought you could get your hands on.
Consider that obituaries, engagement and wedding notices (and photos!) and that this information can help you link to other records which may be more recent and get you past the 70 year wait due to privacy laws, which we all agree need to be in place for the protection of the living.
A draw-back. Misspelled surnames and this time it's not about bad handwriting. One family I research had about 12 different spellings to the surnames as they were reported - birth, death, engagement, wedding, and even one family member who had been arrested in a newspaper, small but the only paper in the Capital of that county. I finally figured it out. The paper didn't have enough letters to TYPE-SET the pages. So in this case there must have been extra O's!
