I see no last name, but his Hebrew Name seems to be "Avraham Zvi Meir"

Here lies
my dear husband and our (dear) father
Our rabbi and teacher Aaron Zvi son of Mr Meier
d 6 Cheshvan (5)678
may his soul be bound in the bonds of (everlasting) life

the honorific implies (but doesn’t prove) he was an ordained rabbi
the last line is a boilerplate abbreviation 

sorry, no surname in the Hebrew

Although faint I see two letters "son of" between Zvi and Meir and agree with David Dubin's rendering.
