Loomis Family DNA Project Update
I would like to provide an update on the Loomis Family DNA Project. We established the DNA Project two years ago with FamilyTreeDNA . A small number of Loomis descendants have participated, which is lower than we anticipated when we started.
But there are a couple of interesting notes that have arisen. There has been a long held belief by the descendants of Joseph Loomis who have involved themselves in genealogical research, that the varying surnames, which looked or sounded similar to “Loomis” might all be related to a distant ancestor.
Two of those surnames recently participated in the Loomis DNA project and here is what was discovered. Keep in mind, this is based on only one test each for these two surnames and may or may not be enough to come to any practical conclusion.
We received a test from a Lomas individual who lives in England and we discovered that for a Most Recent Common Ancestor, we would have to go back in time to somewhere around 500 AD. Since this is based on many assumptions regarding DNA mutations, etc., this figure may have a greater variance and the time factor may be greater. The FamilyTreeDNA MRCA utility showed that there was a 6% chance of an MRCA at 24 generations. Hence I used that to figure that we'd be looking 1500 years out before finding a common ancestor.
A second test results were given us from a Lomax descendant here in the United States. This test also showed a similar chance for a MRCA.
Now, one interesting side light to the Lomas and Lomax test was that when I compared them to each other using the utility, the percentage dropped to about 1%! So, Lomas and Lomax are more closely related to Loomis than to each other, isn't that interesting!
Of the Loomis tests that have so far come in, all showed a very close relationship and a MRCA within less than twenty generations or about 300 years. They all showed a 98% probability in 24 generations which works out correctly with our recorded family genealogy.
What can we surmise from this? 1) That the DNA testing is reliable for determining males who are descended from Joseph Loomis. 2) That two of the similar sounding surnames, Lomas and Lomax, are not related for all intents and purposes. Since finding any kind of written records earlier than the 1200’s is unlikely and time spent trying to tie these two surnames from these two family lines to the Loomis line would be futile.
That should not discourage anyone from those surname groups to also do DNA testing, as there is still a likelihood, that some lost Loomis family may have changed the spelling of their surname sometime over the last 300 years and are in fact descended from Joseph Loomis.
If you have considered participating in the Loomis DNA Project, we would like to encourage you to do so. We are requesting that the 37 marker test be selected as this gives us a much greater amount of genealogical information.
Please visit our website for more details about the Loomis DNA project. Our website is www.loomis-family.org
If you test through the Loomis Project, there is a discount on the cost of the test. At the moment, the 37 marker test is about $189.
