McMahon Family History Website

Welcome to the McMahon Family History website.

The site was created by John McMahon using Family Historian Ver. 7.0.19

It is based on a Family Historian V7 database and is the result of15 years work. On the McMahon side, most of the research is original. On the McDonell side, I have relied on the work of others, particularly Ian McDonell. I acknowledge his work and thank him for it. There are many others who have helped and should be thanked but there are too many to list here. So thank you all.

I have not included any of My wife, Lyn's ancestors. Lyn plans to do her own website.

I have gone to much effort to avoid showing details of living people. Anyone born after 1950 has only basic information. If I have missed one or two, I hope no-one is offended.

Having unearthed so little data about our McMahon Irish history, I thought I’d see if a DNA test might add some light. I had my DNA analysed by FTDNA, a US company, and it has turned up some interesting results. Firstly, we are definitely Monaghan McMahons. Secondly, I have met some cousins on-line mostly from the US. Thirdly, we are closely related to a small group of Monaghan McMahons who have rare DNA characteristics and who appear to be descended from 3 brothers known as the Three Collas who lived in the 4th century AD. Sounds farfetched? Have a look at the website http://www.peterspioneers.com/colla.htm

Choosing a structure for this website has been challenging. What I have settled on for the time being is to show an Ancestor Fan Chart. Then a Family Group Report with all descendants and Family Tree of 5 generations for each pair of my great, great grandparents. I imagined people starting with the current generation, working backwards using the Ancestor Fan Chart, then coming forward using the Family Group Reports and/or Family Trees. Of course, if you want to read about any indiviual you can access anyone on the database through the index.

* This model of Family Group Report and Family Tree applies to all 8 Great Great Grandparent lines except there is no charts for Durham because I have so little detail on that branch of the family.

** I have recently added a link to my family tree on My Heritage. This is an abbreviated tree with only about 200 of the 2700 in my database. If it works, I will grow this tree.

I am very open to suggestions about improving the structure, or anything else about this website. Please contact me using the email address on the contact page.
