Hi again Abdul, It can be a bit confusing when you first start, like most of us, I learned what I know from people on forums like this.
Try this to get you started. On Ancestry click on the search tab select search all records in the drop down menu, type in your mother, Beatrice Bell, born 1893, Nottingham.
The first record you see on the list should be the one I mentioned in an earlier post, another member's family tree with your family in it. Use these names as a guide for your research as the tree owner may have got it wrong. You can also contact the tree owner through Ancestry to compare notes.
The second record is the 1901 census with you mother living with her parents and siblings. Vashti and William E are mistranscribed as Pashli and Wilbain E (this is something you have to get used to on Ancestry
). You may be able to trace Beatrice's siblings forward and possibly find living relatives to contact
The third record is your mother's birth record.
Bear in mind the records you want may not automatically appear at the top of the list so scroll down or narrow your searches using the list on the left to search specific record collections.
Have you managed to find your mother's marriage to George W Fletcher yet? If not, don't forget her name will be Fisher and not Bell at this time. She is there on 1916-2005 index on Ancestry.
If you need any more help just shout, someone will come to your aid.
