Formula to individually sum differently sized groups?
In something I'm working on, I need a way to combine data. The main problem I'm facing however, is that there is a much larger amount than I'm used to (I'm a student in highschool, and I have ~11000 rows of data to get through), and they're grouped into differently sized groups. I may need to sum all of group A (which if five rows tall), B (which is two rows), C (which is ten rows), and D (which is one row), and have each of them represented as one single row.
What I want to know is if there is a function which would allow me to do this, or if I can just do like some sort of fancy merge cells that adds all the values instead of only keeping the value in the top cell.

For an example, I need to sum column E (the far right one) for each individual person in the following from my sheet. However, I need the left three columns to still read "8629,2011, Frazier Todd".
