Im sorry im under the impression you have not read bleach in a long time and most certainly came to the foremost repository on information about bleach and didn't even read any of its articles otherwise you would know this information. Its clear that Isshin is Kaien, Kukaku and Ganju's uncle. Thus making ichigo, Karin and Yuzu their cousins. Isshin was a member of the family and head of a branch family. Thats commonly means he is a younger brother and his older brother was head of the main family. Isshin left soul society and married Masaki Kurosaki taking her last name. She died due to a mix of Yhwach and Grand Fishers interference with ichigo was 9.
