Are there any free resources online to research family documents like fathers last will and testament?
You can only get things online when they have been put online by someone (I guess that is a “no duh” statement). I seriously doubt someone’s (a living person’s) will would be online unless they purposely put it there. Most people keep their wills in a safe deposit box. It may possibly end up online after they have already passed away if it goes through probate. Other documents may end up online (like wedding or death certificates) because they are public record at the county clerk’s office. They might be found online if your county images documents and has a website.
