Been there too!!
My maternal grandfather died before I was born, and gran marries again, so I had very little information to go on - and even less experience!
So, how was I to know that there were 2 Sydney Sims born in Wiltshire around the same time?!

So, I spent some time chasing Sidney George Sims, rather than Sidney Llewellyn Sims - but not 4 years, fortunately!!
But sometimes it is understandable?
Another line I have are the Vanstone family from North Devon.
On the 1851 census, 44% of them share just 7 forenames!
And multiple occurrences of husband and wife having the same names!!
It's a nightmare trying to figure who belongs to who, and I'm not sure I have it all figured out yet!
