Eva Price is Leanne Battersby’s half‑sister on their mum Stella’s side, and Toyah Battersby is Leanne’s adoptive/younger sister from the Battersby family, so Eva and Toyah are essentially related to each other through Leanne rather than by blood.

Core family links

  • Leanne and Eva share the same mother, Stella Price, which makes them half‑sisters in the Coronation Street family tree.
  • Leanne and Toyah grew up as sisters in the Battersby household, with Toyah treated in‑universe as Leanne’s sister even though some fans point out the more complicated technical side of their family setup.
  • Because Leanne is the common link, Eva and Toyah are connected as sisters‑in‑law/stepsisters by family bonds and shared history, not by direct blood relation to each other.

On‑screen dynamic

  • The show leans heavily into the idea of the three women as a tight‑knit sister trio, with writers and cast interviews describing Eva, Leanne and Toyah as strong women who are “even stronger” together.
  • Storylines often play up their loyalty and conflict in equal measure, from feuds over Nick to the baby‑swap/surrogacy plot between Eva and Toyah, underlining that their relationship is emotionally sister‑like regardless of the exact genetics.
