Creating new entry based on combination of two cells

[whattochoose]

Hi!
I'm new to VBA, and I've had a lot of help reading this forum and the extreme knowledge within, thank you all for that.

Now a question that I haven't found the answer to:

I have a column each for id, name, mother and father. I need a new column with an unique id that connects the familymembers. This would mean that every row that has the same combination of mother and father, would have the same family id. How can this be done?

Thanks a lot!
