The Grand Trunk Railroad was extended to Ainsworth in 1880. Ainsworth was possibly named after a prominent railroad official. A post office was opened in 1882 in Ainsworth and closed in 1934. In the early 1990s the area containing Ainsworth was annexed by the city of Hobart. A failed attempt to fight the annexation would have seen the area incorporated into the town of Ainsworth, thus bringing back the name of the old village. It is located near the intersection of
Indiana State Road 51 and the
Canadian National Railway (formerly the
Grand Trunk Western Railroad). ==References==
