Couldn't get Aurilla to come up on the index of census, but found Benjamin Bastin in Jefferson Township, rather made sense she would be there also, therefore went through census page by page until finding her.At least I think this is the one you are searching for.
Found a marriage record for Edward Larkin to Mine J. Smith, maybe Minerva J. Smith?, 6 Jan 1854 (Bk 1, Pg. 554) Edward appears on 1860 census of Putnam, Jefferson Township, Indiana. Did not find Benjamin Bastin/Bastian tho.
Death record for H.W. Larkin, m/w, age 52, died 12 Dec 1893(Bk.H-2, Pg. 25) Maybe this is Hiram W. Larkin listed above as age 10.
This isn't any of my family, just attempt to help others when possible.
