Yes she was a Quincy, that is Kubo's secret revelation. You see the first evidence is when Ichigo was looking at her lying dead by the river; she was wearing a quincy jacket. Secondly he is the ONLY shinigami to have BLUE spirit energy, the SAME blue as a uryuu's. The blanket that his mother gave him on his bed is also a quincy symbol. On top of that you have Issin who shows up at Uryuus dads place and they spoke as if they were past allies from a long time ago and Issin mentions "her" (his wife) as Uryuu's father's sister. Therefore, if she is the sister of Uryuus father she has pure Quincy blood. On top of that Uryuus father obviously holds Issin somewhat responsible for her death. Also, when Ichigo's sister kicks the soccer ball at the menos grande it glows BLUE just like Ichigo and Uryuus sprirt energy!
So I'll break down the mystery for you. Ichigo and Uryuu are cousins, Ichigo is the very first shinigami/quincy hybrid which is why he was able to become a perfect Vizard on his own without Aizen or Urahara doing something to him or using some device. Remember Urahara's face when he saw Ichigo with the mask after he gets Zangetsu? I believe the only people who know of Ichigo's true nature are Issin, Uryuus father and the king of soul society (and by default zero squad). So yes, that is Kubos big secret for Ichigo; he is a hybrid of Quincy/Shinigami/Hollow and contains the highest level of power for all three. That is the strongest Shinigami, strongest quincy and strongest hollow are not as strong as he is. Think underworld (sorry it was the only good reference). If you want it put bluntly, Ichigo is the true Grim Reaper.
