Harringtons in Kildare/Wicklow

I have traced my Dad's family as follows:

Henry Harrington B 1925 Dublin

Henry Harrington B 1898 Dublin

John Harrington B 1864 Dublin

Henry Harrington B Prumplestown Kildare 1809

John Harrington B?

married Bridget Dunne and had 1 son Henry and 3 daughters Mary, Catherine and Anne all living in Prumplestown

I noticed that there are a good few Harringtons in Kildare/Wicklow.

I was wondering if we are all connected especially as there seems to be a bit of a thing for calling boys Henry!
