Anna Sacchetta 1831-1896 LBVL-CWM is attached to a source showing her attached to 2 different husbands. And being born to the same parents as Anna sacchetta 1832-1896 GW8F-L99. Are these 3 all the same person?
These are possible duplicates not yet merged: https://www.familysearch.org/tree/person/research-help/LBVL-CWM
The first one has the same parents but different information - a likely good candidate for a merge. But was dismissed because there is a different Spouse listed. You may need to research if it is possible she remarried or if you know she did not then leave this one dismissed.
The second one has different family information - not a good candidate for merge and has already been dismissed as such.
It is entirely up to you whether you decide to merge them. Usually you will merge them if they are good matches and give a reason why you think they match. There is probably some good Help Center document about how to do a merge carefully.
I hope this helps somewhat - you will probably get some more input from others.
Here are a couple of articles from the FamilySearch Help centre that may help you:
If you assess that these are not the same person(s) you can detach the source from them. This article shows you how to do that:
Hope this helps.
