I could coem up with the reverse of my previous theory? The most logical take seems to be assuming "Rose" is Summer's maiden name but what if the maiden name is "Xiao Long" and "Rose" is her married name (assuming naming works in the RWBY universe simmilarly to what it does in the West in our world).

And yes, I do see the problem of this meaning Summer has an English name but a Chinese surname and that so far all characters names are fully in one language.

So, it turns more or less like this:

Yang is Cinder's and Qrow's daughter. Cinder went evil and broke up with Qrow. For Yang's safety, Qrow hid her with "Summer Xiao Long" who had a fire sembalnce and thus was a beliable mother for Yang. Since Summer is "officially single", Yang gets her maiden name surname. Later, Summer marries a "Mr. Rose" and takes his surname as married name. Mr. Rose has a speed semblance Ruby inherits, alongside his last name.
