Hi everyone
I would say that it is imperative to do a bit of sideways research in order to verify what you find. If you focus on one line it is easy to get the 'wrong' person. This is because so often the same names are used within families. So , for example, if a John Bloggs has 2 sons - for example William and John (William was probably his dad's name) and they both married in the same area and each had 2 sons, they could easily both call them William and John. Therefore there would be 2 William Bloggs's and 2 John Blogg's with probably similar years of birth, and similar places of birth.
If you dont do any 'sideways' reseach, and so are unaware of your ancestors siblings and their families, it is SO easy to latch on to the wrong one - especially if it is an unusual name. You say to yourself well, there cant possibly be TWO Horatious Ponsonby-Smythes born around 1860 in Suffolk!Even though the birth years are a few out, and they give a neighbouring village as there place of birth. When of course, there are two, who are cousins.
Just a friendly word of warning!
