I am a Professional Genealogist and I am a member of  the Accredited Genealogists Ireland (AGI). I am also a member of the  International Society of Genetic Genealogy (ISOGG).

I started working on my own Irish family history in 1997 and I became an accredited professional genealogist in early 2009. Since then, I have done a lot of traditional genealogical research,  especially in County Cork where I live.

Although, I still do some traditional genealogy, I am now firmly focused on Genetic Genealogy (DNA). DNA testing can to be used in conjunction with the paper trail if one exists. If no paper trail exists, then Genetic Genealogy can be  a vital component in tracing family lines.

I am specially interested in the use of y-chromosome DNA in tracing family surnames and in using autosomal DNA to find family. Combining y-chromosome DNA and autosomal DNA can be a very powerful tool in tracing family.

I can advise on which DNA tests to do, what do do with the results, give a comprehensive analysis of the results and advice on what steps to take next. I am not affiliated with any testing company and my advice is impartial.

I am a voluntary administrator of three DNA projects: Ireland yDNA Project , O’Shea yDNA Project  and an autosomal DNA Project:NW Cork Ireland Family Finder Project . All of these projects are run through Family Tree DNA.

    Hello Margaret,

    I live in Stockton, California and am in need of some information about County Cork.

    My 3rd great grandparents, Daniel Derondo Delaney and Ellen Collins, were supposed to have been married 4 December 1849 in Buttevant, County Cork, Ireland. In Daniel’s Civil War pension file he states that he and Ellen were married ” by a catholic priest”.

    Could you please tell me what catholic churches are in Buttevant and where I might find a record of this marriage.

    Thank you,
    Sheri Fenley

    I may be a decsendent of Bartholomew O’Reilly found in Inchineessig in Inchchigeelagh Parish, Co. Cork in Griffiths. He was b. abt 1826 and came to the USA in 1851. I’d be pleased to learn more of him – where he may have been born and who his parents were. His father may have been Michael. His siblings were Jerimiah, Patrick, Catherine, Timothy and Julia.

    Hello Margaret,

    I have found reference to a relative of mine which states:

    “Davenport Comyns late of New York and elsewhere in the Untied States of
    North America, was born on the 17th day of June in the year one thousand
    eight hundred and thirty one, in the city of Cork in Ireland”

    I am unsure in which parish he was baptised (Catholic) though am aware
    his mothers maiden name was Davenport and she was from Co Cork (Davenport was her sons Christian name) and his fathers surname was Comyns (or Commins)

    I wonder if you could advise me as to where i might be able to find information regarding his birth etc
