Hello Alena:
Both of them are right!
but I would say that in your case is optional, see:
If they go together you don �t use the comma - For
example: ...my sisters Lisa, Jannette and Angelina.
If they don �t go together use the comma - For example:
...my sisters Lisa, Jannette, Angie, and the neighbor.
Here are 10 examples of places in which a comma and
the word and belong together:
1.
Maria wrote to
Mom and Dad, and Jeff wrote to Aunt Kathryn in
Milwaukee.(compound sentence)
