As Monica doesn't seem to be around yet, I'll attempt an answer.
Monica possibly ran a parent search at
www.familysearch.org .
You need to register for an account, but it is free. Many records they have digitised are then also free, but sometimes only the index is free and you will be directed to another site that will charge to view.
Once registered, you can run a search using parents names only.
In this case, best adding Ireland to place of birth box, and Alexander Francey and then just Bartholomew for the mum, in parents boxes.
First few returns should be Rebecca Letson (nee Francey).
Not quite seeing her death record at moment, but Monica will hopefully be able to point you to that.
Meantime, possibly her headstone:. see
https://www.findagrave.com/memorial/167254174 .
Ok, update, Monica possibly has a paid for subscription to Ancestry. A quick parent search there in Philadelphia records, returns Rebecca Letson's 1933 death.
Tip:. as you are new to research, it is a good idea to start by familiarising yourself with which sites are available, which offer free records, and which only offer paid for records. It can be a minefield, but you should soon become proficient at finding the best way through. Once you have exhausted free resources, it can be worthwhile considering a subscription to one of the major sites such as FindMyPast or Ancestry, depending on which might suit your needs best (and of course, cost).Both often have 'taster' style, free trials for short periods, so you can try before you buy.
