I want to thank you for the help earlier this year on this matter.
I have discovered the Ellen Farrell who died in 1912 is the correct one based upon address.
Based on the census, it looks like Ellen couldn’t read/write - so I’m guessing that could be why the various misspelling of her name occurred.
I still haven’t managed to find John, but as you say - he could have been Owen.
Thank you again for the help, will keep trucking on
