I need help identifying this brand mark on my horse

I just bought a new mare and I was just curious about her brand mark. It is a capital M with a four made into it. I will email pictures for anyone who asks. It has to be something like "Rocking" something because isn't that what the curved line means? anyway, i don't pretend to know much about brands and I was curious about her brand and her past.

Thank You

Sarah

I would love to see a picture,, i would also like to know where you got the horse from the breed and anything else you could tell me, defining brands can be very hard especially since some people have private brands.

This is from a website on the matter if it helps at all -

One question that is often asked is "My animal has this brand. Where does the animal come from?" or "What is his history?" The authority on brands in your area is the local brand inspector. If you think a horse came from a different area you can contact the brand inspection board for the state that you are interested in. The brand department is usually under the jurisdiction of the state's department of agriculture.

These professionals have the records to check to find out who owns the brand in question. Also, if you find a strayed animal, the brand inspector can find the correct owner. Conversely, if you lose an animal you should contact the local brand inspector with the brand and description of the lost animal. Some states, such as Arkansas, have brand registration, but it is not mandatory and many brands are not registered. In that case, the registered brand takes precedence over a non-registered brand in case of a question in ownership. In states without brand recording laws, state livestock associations (like the state's cattlemen's association) can often be helpful.
