Deceased grandmother stocks question

My grandmother had 35 shares that she had purchased from the ADP, the company she worked for when she was alive. She passed away and my mom told me that she never did anything with that. They were in a Charles Schwab account but now the state has it as unclaimed property. My mother has passed away and from what I’ve been told I am the heir of these stocks. My question is this: The 35 shares have been in limbo since 1999 or so. The stock has split 3 times since then. January 4, 1999: 2-for-1y April 2, 2007: 10000-for-9033 October 1, 2014: 1139-for-1000 Do the 35 shares on limbo split as well? If so, according to those numbers we would have 77.49 shares? Hopefully this makes sense, added as much info that I have currently. We called Schwab but they were no help as the account was closed in 2000 or so.
