Progressive List for Family Placement in a Grid

I am trying to place a bunch of family instances based on an Excel file. Each family type is placed in a row, with the next family type placed above in the next row. I’m almost there, but can’t figure out how to increase the y placement points progressively by the previous family type’s length.

Similar thread, but images missing so I can’t figure it out: A simple progressive list - Fibonacci Sequence
