I think Isshin took up the name Kurosaki upon marrying - but then I assume that Masaki´s family ran the Kurosaki clinic for years before Isshin lost his powers 20 years prior to the start of the story. I also assume that Urahara found Isshin an gigai to use while powerless and that gigai is the reason Isshin stayed powerless all these years (vol.22 ch.188 page 8) But as Urahara states that Isshin "abandoned" the form of a Shinigami 20 years ago.... I wonder what really happened. Also, as (at page 11 same chapter) Isshin states "that crimmnal group of ex-shimigami that uses forbidden spells... ...we never found their base..." it seems clear (to me) that Isshin knew about the vizards and was maybe activily involved in searching for them, but never did know the truth about what happened to make them vizards.
