Family A is always welcoming, always helps a stranger in need, helps their neighbours, but above all they follow all the customs and traditions because that's what they were taught and it's important to them. They are lawful good.
Family B also welcomes strangers if they come asking for help but doesn't go out of their way to help people, they do it because it's a custom, they only help their neighbours because that's how that village has always been taught to, however they mainly look out for each other and aren't very concerned with actual well being of the ones around outside of following those moral and social values that they were taught living there. They're lawful neutral.
Neither of those knows much about the actual law where they live, though they would most likely know about how much taxes they have to pay, but they both follow the rules placed upon them by the environment they were created in regardless of their personal views on it making both lawful. Now, if family B only followed those rules out of social obligation and not because it's how things should be done they would be neutral rather than lawful. Alignments aren't strict rules, they are guidelines meant to help figure out basic way of how a character behaves, but actual people have a lot of depth that is impossible to cover with that simplistic system.
