Hopefully you will be able to follow this.
Lets start with Herbert Vaughan and Sarah Griffin
the first thing you need to do is find them on census -from census after marriage until death.
That way you will find if at any time other family members lived with them -which can help in your research.
As you are a member of ancestry I will leave that up to you.
If you look back over these posts you will find I have already posted the 1861 census -Herbert and Sarah with 5 children. The eldest child being Ellen Vaughan age 13.
(after I posted that you have posted that someone has just told you about Ellen Vaughan -and you didn't know about he?
)
If you had gone through each census year you would have known there was an Ellen vaughan - also if you had read my previous posts thoroughly you would have known that too.
You have to take it slowly
By the age given of Ellen on the census it seems as if Ellen was born before Herbert and Sarah were married.You had found their marriage reg
So then there is the possibility that Herbert had been married before and Ellen was from a previous marriage.
If you had purchased the marriage cert (which is always a good idea -as it would tell you if the bride and groom had been married previously -it would give names and occupations of fathers of bride and groom -unless they were illegitimate. Even if they were illigit sometimes the fathers name is entered -if the father was known to the bride(or groom) The marriage cert may confirm John Ennis is the father of Sarah. Also witnesses are sometimes relatives -and so give further confirmation you have the correct family
