Before play started
We are playing young members of a traveling troupe of mummers/etc., who were attacked by the local inquisition. Before play we visited a certain town, but it has not been established if we performed there or simply passed through.
Current situation
My character's lifepaths are born peasant - apt pupil - augur (no affiliations or reputations) and I'd like to test circles to find some local healer whom I could help for a meal and place to stay for night. By the rules, is this a legit use of circles? If yes, are there obstacle penalties compared to finding such a person in some location where my character actually lived in for longer?
More generally
Can circles be tested to find people who (for example) share a profession, even if there is scant reason to believe they have had any significant interaction before the roll?
The game is played using the Gold edition, but supposing the circles rules have not changed much, revised edition responses are likely to also be useful.
