That looks good.
The difficulty is, peb205, that there is a lack of information from your posts.
The first post gives Mary Ellen with year of birth and likely parents but from your previous thread, it has now been assumed that it is perhaps this later Mary Ellen.
When information was offered, you just wrote that you were confused and reiterated that you still hadn’t got the grandparents.
If Mary Ellen married, her marriage certificate would show her father’s name which may well help in the search.
You mentioned a census but gave no indication of that despite being asked.
I hope you can see that you do need to give as much information as you know and sometimes have to purchase certificates. I appreciate that it is your friend who have to do this.
Hopefully, keyboard has found the Mary Ellen you are looking for and her parents, your friend’s grandparents, so you could then go back further.
