At first, it struck my interest for a couple reasons: he's an iceman named Lanzillotta! his name is Nicola! (Grandma has a brother Nick . . . )
Then I looked closer. Oh yeah, he also lives in the same house as Grandpa Lanz, who was presumably his brother. When I asked my mom, she said she remembered Grandpa Lanzillotto having a brother named Nicola, but couldn't volunteer the name until I mentioned it. I'm going to have to talk to Grandma to confirm that.
Like his brother Carmine, Nicola's address was 281 E 155th St., in the Bronx. He was born 9 May 1884, and was 34 in 1918, when he registered with the draft. He was white, Italian-born, alien, of medium height and build, and with brown hair and brown eyes. He was an iceman at 890 Morris Ave, which appears to be about a 20-minute walk from his home. He's married to Maria Lanzillotto.
