This doesn't seem crazy to me if the rate of mixing is high. If the Irish were 3% of London at one point, and each person with Irish ancestry always procreated with a person of British ancestry then it would take about 5 generations for half the people born to have some Irish ancestry. You could see that happen in a little over a human lifetime.
