Maybe not.
I couldn't remember below the age of 7 and there is also a house we lived in and I can remember small bits of the house we lived in just prior and a few bits of the house we lived in directly after but not that house. To a point where I handed my dad a picture of the house and asked "whose house is this"? There is just a black hole in my memories while living at that house. I don't even know if trauma happened there and if so, what that trauma is.
Before therapy I had very patchy memories. Many missing pieces. Where they made little sense. Today they are sharp all the way down to smells in the air and sounds and what was on tv. That said, I still can't remember below the age of 6. Ages 7 and 6 are super muddy. There was trauma there (and before then which I cannot get to) and though I partly remember some of the trauma, it's all super muddy and merges into itself.
Memories are intresting. You can actually create false memories without realizing it that feel just as true as the others but they aren't.
You may get some memories back of your dad before he died but sometimes a trauma is just too much that our brains hides it from us forever. I was only able to recover the correct memories and correct the false memories by working with a trauma therapist.
