This criticism may be a little silly but it is strange that the mc don't know Sirius and consequently Harry since the former is a close friend of his uncle, even more so since probably Sirius wanted Harry to have a happy childhood with friends and all, so what better way to socialize than with children related to the Order of the Phoenix and the like, unless alaric and sister were not in the country before the tragedy and I missed that explanation
