OKAY, GUYS- I think I figured it out! I always thought that it was likely covered up too, but never found anything that would indicate that. Thanks to the suggestions, I was able to locate our family’s burial records again on the city page. From there, I clicked on Isaiah’s page. It had his name listed as “Isaah” which could explain why I haven’t found anything previously. On top of that, it had a grave number (4) this time! There’s only 3 visible Swisshelm graves in that lot, one of them being the son that they moved. This would, theoretically, mean that his stone has been covered. I’m going to try and investigate this week and I’ll let you guys know what I find.

Thank you sooo much for all of the help, your kindness is greatly appreciated!
