When doing some BMD searches I came across a strange thing.
My GG Gran/Granddad had a child who was called John Donnelly and born 7/4/1896 and died in ww1 4/7/1915.but I found another birth and death entry for another John Donnelly( born to the same parents)
Is it usual to name your younger child after its brother /sister?.Ive never came across it before.
