Jimmy :

I found a death certificate for a John Moran DOD 18 Dec 1909

(significant because your Great Grand Mother was a widow in 1910)
Also significant over the years your family lived near or on East 135 St in the Bronx as did this John Moran.

Death Cert for this John Moran age approx 45 , this is close to birth date of Oct 1863.

per the death cert the parents of (John Moran) are John Moran and BRIDGET BERRY
Is this where the "B" comes from ?

Now we need to some how confirm that the BERRY family is in your family tree !

Do you have any Berry relatives or family stories/HINTS ?
