Maybe we do things a little different where I?m from but normally a godparent should be a sibling or cousin of one of the parents or a very close family friend. The most important thing is that it is someone who will take a moral responsibility for the child should anything happen to the parents. Other than that all it really just entails if a banknote in a birthday card once a year and attendance at certain events like 21st birthdays, weddings, confirmations, bar mitzvahs, trials etc.
