Hello Vienne,
The information you have collected is astounding. Since my interest lies in History, I wanted to confirm one detail that you have mentioned under the column "Glasgow/Scotland":
Albert Hudson, editor of Bible Study Monthly, a British Bible Student publication, says that the first organized meetings were in Glasgow starting in 1883. He presents no other details
However, I found some information mentioned by AO Hudson - when I was going through in the following link :

Now, in June 1882, little more than six months after the distribution of the booklet in this country, a dozen people in Glasgow, chiefly men folk, commenced to hold a regular meeting for the study and discussion of the Bible in this light. This was the first Bible Students’ meeting in this country, so far as records and recollection can tell. Rather appropriately, perhaps, it was a humble beginning. The organizer and leader of this initial meeting was apparently a man in a lowly walk of life—his name is lost to history—...
I am not sure but wanted to confirm from you which of the dates is accurate: 1882 or 1883.
