Im not sure if this is what your looking for, and I have no relation. I live in Anne Arundel County Maryland (In an area that is only a stones throw from being Baltimore County). In an area that is not overly populated.(I live on Ingrahm Drive ). My road is named for the cemetery that is located just at the beginning of the road. The graves are very old from the early 1800s to as late as 1860 I believe. Most all the names on the head stones are Ingrahm. Not sure if these are those whom you could be related. If it is, I am more than happy to walk down there and take pictures of the head stones for you and email them to you. If you think they may be something you can use.
