Originally a male name, along with Allison. Should be reflected in the main page for the name.
Just because it has "Alli" or "Son" in it doesn't mean that it's a boys name. "Alli" can be a girl's name so if you are one of the people that said this and think I'm wrong then check this out, (I looked it up on the internet) because it's as much as a girl's name as it is a boy's. "It was popular until the early 19th century and, spelled Allison, was the 45th most common name given to baby girls in the United States in 2005 (Allyson was #253; Alison, #259; Alyson, #468; Allie, #256; Ally, #656; and Alice, #414).""Total* Population in Top 1000: 235281 (0.65% male, 99.35% female)" This is for a girl... "Total* Female Population in Top 1000: 233754" This is for a boy... "Total* Male Population in Top 1000: 1527" SEE THE DIFFERENCE
In Scotland, by 1900, Alison ranked 66th. Fast forward half a century later and it rose up to 40th place. Though it wasn't as popular in England in 1900, by 1950, it also became more popular there.Looking at the 18th and 19th century censuses from Scotland, England, Wales, Ireland and the United States, it seems quite clear that Alison was sort of commonly used in Scotland in the 18th and 19th centuries with some of the Alison's recorded in censuses from outside of Scotland originating from there, so it seems to me that the name may have been reintroduced to a wider population throughout England and spread to other parts of the UK & Ireland and the English-speaking world in the early to mid 20th century via Scotland.
