Thanks Ken that's what I was thinking too!
The old 2x4's are much larger than present day but still they ain't that strong esp. after 122 years.
If some of the ceiling joists are sagging, others will likely soon follow. Sister them all and be done with it! Of course you need to take into consideration the additional weight load from the new lumber added, so maybe you should remove/replace all the ceiling joists. Go to HGTV and ask Mike Holmes!
