Hi Nieve,
I paid a visit to St Helens Library today and lo and behold there was a Sutton Rd InRainhill after all. Although the lady could'nt give me an exact location on the map we do know where abouts it was as it was in the indexs.
I also mentioned you could'nt find where Ellen had been buried ,the lady said she could have died in Whiston Hosp just up the road from Rainhill that Hosp comes under Prescot borough where there is apparently a cemetery but in the Protestant church. There is however 2 very old churches in the Prescot diocese both catholic, not sure of the name of the one in the centre of Prescot but the other is Our LadiesRC Church Portico Lane, Prescot. The lady also said Whiston Hospital was also a workhouse so if she was'nt well they would have taken her there.
Also regarding Church Villas , although again not sure of exact location but in the index's it was near a church and school so we have a good idea of the location. I have got photo copies of both locations if you would like them send me your address and I will forward them onto you as unfortunately I dont have a printer or a scanner at the moment.
You could also try writing to Prescot library where they have quite a few records, also have you tried Prescot reg office for a death cert. The address of the Library is Kemble St , Prescot also same address for reg office. Hope you find her . Best Wishes Caroleoh, let me know if there is anything I can do to help
