I am looking for help or guidance with something located on my parents 100 plus year old (we believe early 1900's, maybe earlier) brick home. They live in IL, just east of St. Louis, MO and have owned their home almost 30 years. We have never found out what a symbol on the outside of the house (where the chimney is) means. The symbol looks like a block lower-case "m" with the center leg of the "m" longer than the two side legs. And all of the legs end with crosses on them. Any information you can provide would be most helpful as my parents are thinking about downsizing soon and I would love to be able to answer this long standing question for them.
