McLaughlin Origins - Part 1

My interest in heraldry information has waned a bit.  I am more interested in reviewing the origins of my various family surnames.  Sometimes the brief heraldry information is all that I can find.  For my McLaughlin surname, I seemed to have found more than the typical paragraph or two.  I found a 30 page document online.  It contains a lot of names but does have some interesting information.  Could this be the line from which my McLaughlin's descend?

The Donegal McLaughlin's based their surname on an ancestor named Lochlan who lived about 1020 A.D.  His grandson was Domnall MacLochlainn, the high kind of Ireland who died in 1121 A.D.  Domnall is found in the "Annals of Ireland"  under the names Domnall Ua Lochlan and Domnall Ua Neill.  The origins may be Norse.

In 1260 A.D. Ireland, there was the Battle of Druim-dearg, near Downpatrick.  The O'Neill's and O'Connor's were fighting the English in the northern part of the country.  Many Irish chieftans were slain during this battle including Dermot MacLoughlin.

I find the census information from the 1600s to be very interesting, although, I need to get a map out and see where all of these places are.

It is interesting what can be found online.  What did I find though?  I found part of the 1659 Census for Ireland that counts the instances of the surname McLaughlin and it's variants.  There are 15 in County Longford for the exact spelling of my family surname.
      
I am wondering if there is a possibility that I may be able trace my McLaughlin's from the past to the present.  Michael and Patrick McLaughlin immigrated to the U.S. around 1823.  Is there a way to use the 1659 Census of Ireland to find the McLaughlin's and link the family line together somewhere in the middle around 1790 to Thomas McLaughlin and his children Michael and Patrick?
