Yes! Do this, because it is not always just cash

When I checked the website years ago I not only found THOUSANDS for db and myself I discovered it was coming from oil royalties that some how my dgm lawyer had missed when transferring them around in estate settlements. One of those royalties is what I get my little monthly checks from now, db gets checks too and has helped me do a lot of research since the first nearly $6,000 I found for us to split.
Also besides your name, check your parents, grandparents and even great grand parents, aunts and uncles and your children (you never know what might have been willed to them without your knowledge) in EVERY state they ever lived in. I live in OK, but found some money in MO. It’s simple enough to claim and worth the effort.
