Mer'Cauthon Orphanage.
There are 26 orphans, aged between 5-13 (Kester), with slightly more boys (15 of them to 11 girls). They are all human.
An unskilled worker typically earns about 1sp per day, which would equate to about 2gp per day if you want to keep the oprhans in this level of lifestyle. I would suggest, allowing for bulk buy in food etc. that you could maintain them for 5-10gp+ per week, obviously the more you spend, the better their lives will be and the more likely they will be to stay rather than return to the streets.
Current adult population that I know of are Edmond and Brindom, can't recall if Manachan is bedding down there as well. Dj'hân visits but is not a permanent resident, and I think Thorson has his own place at the dwarven smithy. Jeremiah has agreed to be a tutor but still lives in his Shingles residence.
