thank you Larry and Ken!
However I am still stumped and would appreciate a bit more help. I did indeed find the ‘page’ in the trash and deleted it. But I still cannot get the edit (dropping the ‘-2’ in https://rocklake.org/turtles-2/) to stick. I have purged the ‘SG Cache’, logged out and back in, and hit update from the pages menu. I also checked the ‘settings’ and did not find one for this type of function. When I do a search for ‘turtles’ in my list of ‘Pages’ another page (HealtyLakes) does show but has no trace of the word ‘turtles’ in it.
