LINTHICUM SURNAME DNA PROJECT Your help is needed
Posted by: Terry Linthicum (ID *****0542) Date: June 22, 2012 at 15:18:26
In Reply to: Announcement of the LINTHICUM SURNAME PROJECT by Terry Linthicum of 699

I guess I should not be surprised to be at this point given the lack of response I’ve seen on the subject to date but I will persist just a bit and move forward with this update and a bit of a plea. I have no financial interest in FTDNA beyond my purchase of the test kit and chose them because of their standing in the field and the “free” services they offer like the surname projects. Most ancestral based y-DNA testing done by other companies can be compared through sites such as y-search. If any readers bearing the LINTHICUM (or variants) surname have had a Y-DNA study done, please consider sharing your results.

This could almost be a cautionary tale. If you have researched your line very thoroughly and are confident in your findings then maybe you should just leave things alone and let someone else worry about all those other issues. However, if you are adventurous, altruistic and investing another $150 or so in your family research wouldn’t cause you financial hardship or seem foolhardy, please read on:

I have received the results from my 37 marker y-DNA test and they are posted at the Linthicum project at FTDNA (see earlier announcement) and also at y-search. The only other previously tested Linthicum responding to a mailing from FTDNA was an individual who submitted a sample that was tested at the12 marker level. He submitted his sample several years ago for another program that has the goal of mapping the “human genome”. His results are also posted at the group site.

There is a Linscomb sample in the works with results pending and I am expecting a Linsicome sample to be submitted soon.

Herein lies the rub: The submitter of the 12 marker sample has done little ancestral study where I am fairly confident about my Linthicum lineage (on paper) clear back to Thomas the immigrant. He and I have so many mis-matches at the 12 marker level that the odds of our being cousins within hundreds of generations are worse than those for winning the lottery. With only two samples, this proves exactly nothing in the larger picture!

FTDNA and y-search provide other tools for finding genetic matches and this is where things get really interesting and confusing: Searching at the 37 marker level and screening for very low levels of mis-matches, my sample is an exact match with one individual with the surname HUDDLESTON and very close matches with several other individuals of this surname. My very preliminary investigation shows that Huddleston researchers trace their origins to various locations in England back to about the 1630’s and there seems to be little if any common geography with my line in America but again, without additional LINTHICUM samples for comparison, this is cause for all kinds of speculation but presents no viable and actionable path for further genetic investigation.

Again, simply stated, your participation in the study can be of great help to others (including me) and the more samples that can be compared, the more we will learn.

Thank you
