Yes, that is why I wrote that women of that time were "not employed" not "not working". Household chores can be considered work, but that brings into question what is work and what is leisure? Raising kids is certainly a lot of work but it is also entirely optional so why isn't it leisure? arvinism however wrote "more time at work than ever" which can't mean anything other than hours in employment.
Doing a load of laundry on a hand washer and scrubbing board takes forever and is pretty brutal. So is getting up super early to put coal in the furnace (and then keeping it going all day every day). Running a stove you have to load with wood means starting really early. Churning butter by hand. Possibly grinding flour by hand. Making everyone's clothes by hand - when the sewing machine came out it made Singer incredibly rich because it saved so many women so many hours sewing their family's clothes by hand.
Nearest extant comparison would probably be Amish women.
