I think Summer Rose is Ruby's mom, Ruby's dad is Yang's dad, and Yang had a different mom. Ruby took her mom's surname because they lived away from her father, and Yang took her father's name. When Summer Rose died (maybe against grimm) Ruby was still very young (maybe 3 or 4) so she went to live with Yang and her family, explaining the different names and Yang reading to Ruby when she was "young"
