"" "" "" Regarding Mary managing Lincoln's salary, "In contrast, the Lincolns lived on $6,600 a year, not much more than they had spent during there last years in Springfield. Under Mary's direction, (for her husband was negligent about money matters) they saved $70,000 of his $100,000 salary, less $3,600 for taxes." (page 192)" "" ""

Is this mentioning their family spendings while in the White House?
If so, the general admittance that AL was a frugal man is no legend then.
