Questions about households vs. individuals

Going through documentation in preparation to stage our data, and we hit a couple of questions:

 

§  One of the v11 training videos stated: “if affiliate record doesn’t have contact info, it inherits from the Household’s primary contact information. The only inheritable contact information is: home address / phone / email.”  We use custom phone types specifying N1 Business, N2 mobile, etc. So the question is, are our custom phone types inheritable, or is it requiring one of the standard Phone 1 / Phone 2 / Fax values (that we don’t use)?

§  Regarding Household creation: of course, samples giving say “if John Smith is N1 and Jane Smith is N2, the name assigned to household will be “John and Jane Smith.”  What rules are in place when Last N1 and Last N2 do not match (i.e. John Smith and Mary Poppins) or those few accounts where it’s elderly siblings living together (i.e. Laura Jones and Betty Jones, who shouldn’t be listed as Laura and Betty Jones)?

 

Thanks!
