The name refers to the House of Lancaster

During the Wars of the Roses, there were two houses, both with a rose as their symbol and both were the homes for knights since those were medieval times. Since Ruby's a Rose while Jaune's a Knight and the House of Lancaster holds these two traits, Lancaster became another way to refer to Rose Knight in the RWBY community.
