My setting is roughly mid 1800's and obviously London and my questions are:
1) What would have been a good working-class neighborhood in London in that time period where a German woman could run a boarding house?
2) How would a young Victorian gentleman of roughly 30 or so properly address a polite but warm letter to a older woman not related to him by blood? Think like an adopted mother type scenario. They are both middle class and the man is reasonably well-educated
thank you in advance
