MCMAHON, Patrick born 1805

Hello!

I am new to this parish as I just found out today that my 3rd ggpa is from Carrigaholt, Moyarta.  I have info that he shared property called Rinemackaderig (Rathmacderig) with Michael McMahon and Micael Behan. 

I only know that Patrick's DOB is 1805 in Co Clare and died 1870 in NY (he is buried in Holy Cross cemetary in Buffalo, NY) 

He married Mary Lynch.  They had 4 daughters,

Bridget McMahon Doyle

Katherin McMahon Behan

->>Mary McMahon Lynch (my 2nd ggma who married Michael Lynch (my 2nd ggpa) om 18 Jan 1859 in Hamilton Township, Wentworth Co., Ontario, Canada.

Margaret McMahon Dugan

And possibly a son named Simon

**I would like to find information about Patrick's place of birth, marriage to Mary, emmigration, etc.

If this matches any of your information I would appreciate any help.  I've been on Clare Library for 3 days, found Griffiths Eval, very limited info on Ancestry.com

Sadly the origin of this info came from the Library Forum which I am not allowed to respond/reply to??  I am registered as a user so I don't know if it's no longer working or?  When I registered I was unable to do a search or see any or click on any forums..... they didn't exist for me.  I could however read them once I logged out.  I am baffled.

Thank you and kindest regards,

Karen
