house now standing on this lot bears little resemblance to its original
form. Cleveland believed this was William Cornwell's original house, built
when he arrived in Penn Yan about 1815. It was instead built sometime before
1824 by Cornwell, perhaps as early as 1819 when he married. The first house
is the core of the present #325, and his second house forms the core of
this one.
It was enlarged into
an Italianate mansion after Cornwell died in 1848, possibly in the mid-1850s
when that style became popular. It was then two stories, with a shallow
hip roof. The remodeling may have dated however to 1863 when Sarah Cornwell's
son George R. acquired the place for a nominal sum and leased it back to
his mother for life. Sarah and her son continued to live there for decades.
She died in 1888, having
outlived her husband 40 years. It was then that the third story and the
present roof were added, and the front porch enlarged and embellished, turning
the house into a Queen Anne mansion that was retained by the family until
well into the 20th century. M.S. Lounsbury bought it in 1926 from Mary Cornwell
Palmer, whose family had lived there for more than 100 years.
