2014 World Population – Gallagher (based on data by Forebears)
An approximation of the numbers of surnames residing all over the world has been arrived at by an organisation called Forebears. They have then used these figures/statistics to create distribution maps of various surname holders.
I have used those for Gallagher (not including variants, which must be created separately) to produce a distribution document to enlighten people as to where Gallaghers presently reside, where they were in 1881 (UK) {1880 (USA)} and a comparison can be made between the results for the two years.
Hopefully, as time goes by, through work being carried out as part of the one-name study, these figures can become more definite and further analysis will lead to further information and greater understanding of the Gallagher story.
