Albert Otis Hollis was born around 1841 in Massachusetts and by 1860, he was working as a boot maker. He enlisted in the Union army on August 8, 1862, and mustered in as a private in Company B of the 43rd Massachusetts Infantry on October 11. The regiment was stationed in New Bern, North Carolina, and Hollis mustered out on July 30, 1863. He returned to Braintree after the war and resumed his work as a boot maker. In 1870, he was living with his brother William, who also worked as a boot maker. In October 1879, he was charged with “lewd and lascivious behavior.”
He married Carrie C. Barnes in Braintree on May 29, 1880. They settled in Quincy, Massachusetts, before moving to Attleborough, Massachusetts, sometime in the late 1800s. He applied for a federal pension in November 1897 and received one the following year at a rate of $6 per month. By 1900, he was working as a farmer. His wife died in 1904. He remained in Attleborough for the rest of his life, and he retired sometime in the 1910s. He died in Attleborough on August 7, 1923.
