My condolences on the loss of your father. I am sure he would be very proud of your achievements and ambition to attend Stanford.
I don’t think your sending an email would have any benefit. Stanford yielded 80% of accepted students last year, meaning the vast majority of students who get accepted to Stanford viewed it as their first choice.
In other words they know they are awesome, you telling them it probably doesn’t move the needle.
Best of luck.
