Would make sense considering I believe that they would have all passed away at relatively close times. Though I have no record, I have seen censuses that have Malcolm living at 1891 where he would have been roughly 80, so I assume that he died between 1891-1895. Chrissie died in 1907, and Herb died in 1911. So they are all relatively within a close time frame. Being a poor family, it's likely they would have not been able to afford a stone for the father or boy. A shame, really. Wish there could be a way to pinpoint exactly, but records on the matter would be awful limited. Thanks for the info!
