Thank you ashepheard for your help and I am certain that you are correct in your findings, and it amazes me to read all about this, it was with great joy this morning that i was able to fill in the gaps in the family tree and to confirm my great grandmother's maiden name ! Thank you for all the additional information too, I am so amazed and only wish that there were photographs to go with the people, how fantastic it would be. Its weird how affectionate you can feel towards a mere name when you know that were it not for them, you wouldn't be here yourself today.
THank you very much for submitting me information that i don't have access to myself currently.

Thank you Noggin for your help and for taking the family records even further back, you have been so kind to share this information to me, and I look forward to plotting this data into the family tree I am building, and look forward to seeing it printed out and framed or laminated and preserved that way. YOu are very kind to help me like this and it was super to read the names of Charlotte Heyes and her forefathers.. or foremothers, well, her family. It is interesting to see the surname Tasker, because my grandfather's brother, son of Charlotte Heyes, and Walter Sanders,
born 1903, well his brother was called Arther ( Tasker ) Sanders, and I actually met Uncle Tass many years ago when i was a child, since he was the second youngest..my grandfather being the youngest. I always thought is a curious name, Tass, but ,now I am even more curious, because this is the surname of the first wife of her father... Anne Tass, who became Anne Heyes.. such a connection is curious and one wonders if it was to please her father in memory of Anne. However, was her father still alive in 1903? Thank you again, for your help, and sharing that which i am not able to see at present.

Thank you very much.

hello Noggin,

I read this very late last night ,and again am looking at it this morning. It would appear that there is a child John Hayes, who does not appear on later census ? This suggests that he died ? He was only 1 years old in the 1861 census, but does not appear on the 1871 census, does this suggest that John died before the 1871 census ? Can you find out ? I am very grateful to you for all that you have done .

There are a number of John Heyes death betwen 1861 & 1871 for Prescot. The one below
is the only one showing an age at death. This might be you John but the death was registered Apr-May-Jun. The census is usually taken in the 1st week in April so he could have died before the census.

Death

Name: John Heyes
Registration district: Prescot
County: Lancashire
Year of registration: 1871
Quarter of registration: Apr-May-Jun
Age at death: 10
Volume no: 8B
Page no: 555

Thank you Noggin for death details regarding John Heyes.This does tally with the age of death and reference to birth on census..estimated, and districts. .pity the parents names are not given. I am cataloging the information
as you have provided it and it is shaping up very well.Thank you for your help . any further evidence would appreciated. ..if there is a way of confirming poor young John Heyes short life I would value it.
Thank you fir all your gelp so far it is priceless!

Would registration of death be available for Mathew Heyes father of Charlotte Heyes, married to Ann Tasker 1856 and Susan Symonds 1871?The latest record of him is the 1881 census when he was 45.I know you have helped me so much already..this detail would be helpful for the family tree...I think it would complete the relevant blood line dates for the maternal side of William Herbert Sanders...Mathew Heyes being I believe his maternal grand father.
Hopefully it will be possible and thank you for all your previous assistance.
