I agree with Lorenz that you probably want to look at SPARQL CONSTRUCT and more
specifically CONSTRUCT *WHERE*
(https://www.w3.org/TR/sparql11-query/#constructWhere).
Your query would become:
CONSTRUCT WHERE {
?person :LastName; :FirstName ?FirstName; :Address ?Address .
?Address :Street ?Street; :City ?City; :State ?State; :Zip ?Zip
}

Subject: Re: Returning a Triple from a QuerySolution for each Solution Variable
Not sure if I understand your question, but should you just use SPARQL
CONSTRUCT queries if you want to get triples?
