If you live in the area, next spring be watching for this event. They do have a website so you can look at it and bring up the information about it. Currently it has this year's event that just took place last weekend. But it will give you an idea on what they cover.
In the mean time, the Jones Center for Families in Springdale has a room set aside for researching your family history, staffed by local LDS folks and other volunteers. They are very helpful. I have used their research centers a lot down through the years. If you are worried about proselytizing they do not do this. These locations are open to anyone doing research on their family. Look here for their website and further information.
Maybe these websites will lead you one step closing to busting out those ghosts in your closet. So, as always, Happy Ghost busting!
