There’s a ghost in my grandparents old house, they’ve all seen him, I’m next…

A few times each year for multiple days me and my family go down to my grandparents house in Cumberland county Il. Theres a like 70ft rock driveway leading to the front of the new house. On the right is their old house which is like 5 feet at the corner closest to the new house. My father, uncle, and aunt all grew up together in that house. It was built probably in the late 1880s or 1890s. It’s full of cool old things. Not huge piles but kind of like moving into a new house amount of stuff. They don’t really care if we take things from it or not (as me and my cousins mostly do). So it’s sometime in April or May I’m down there with my father and one of my favorite cousins. Me and my cousin go into the house because she recently bought our old great aunts house and it fixing it up so she needs money for fixing it, hence why she’s grabbing stuff from the old house. We search first in the frunchroom (living room) and then we go up stairs. On the close left is my aunts room which extends backwards behind you on the other side of the wall. On the far left was my dads room which goes forward. To the right is the massive room that used to be my uncles bedroom. We go into my dads old room and find a box of photos we take to the family sitting on the porch outside (uncle, aunt, both grandparents, and cousins. They thank us for finding it and the family goes looking through it. Me and cousin go back into the old house. She stays in living room and I go back upstairs. I spend a few minutes in my dads old room and head downstairs. I hear what could easily be mistaken for foam board moving (there was old bungee corded to the wall in front of me) so when I stopped to look at it you could imagine my rising panic and confusion when I see its completely ice still. I still heard it while looking at it. I raced downstairs the rest of the way, through the dining room. And into the living room where my cousin was. I didn’t say anything and continued searching the living room. Eventually me and her left and put stuff we grabbed in our cars and went over to the family. My grandpa started telling stories of when my uncle was born he saw an old man watching over him at night in uncles room. He would also hear footsteps multiple times a month while the kids were 100% asleep. My grandma also told similar stories. Aunt added how her window would constantly be opened at night or during day (happened to dad and uncle too just not as much). Aunt and Uncle told of how they would be covered back up after kicking their blankets off multiple times. They believe they have had hundreds of subtle experiences with this ghost. They said they eventually got used to it instead of being scared. (I hadn’t told anyone what I experienced before btw) My mom also used to go over to my dads house and even she experienced weird things. Looking back it sounded like heavy wood object being moved on a rug in my aunts room. (had the most activity btw) I believe i found out who the ghost is.

I believe the ghost was a man named William

he was a chill guy who let kids fish in the creek on the property (grandparents property now) sometimes he would even fish with them.

I expect to go there for thanksgiving if not though 100% will be down there for Christmas (as it’s a family tradition and has been for decades)

He does actually sort of take care of the house too. Everything is always mostly good condition or cleaner and it’s interesting. Anyone else have something similar happen?

(for context they moved out of the old house in the early 2000s after a storm knocked a tree down on the roof but the house was repaired without sustaining significant damage)

Any suggestions on what to do?
