About us

The purpose of this project is to establish a DNA repository for the Calvert Surname for as many Calvert Families as possible, regardless of the spelling of the Surname. Due to known circumstances, especial related surnames are involved, such as Harris(s)(son). There are other possible connections. For the Lords Baltimore, we do not have a primary source documented male descendant who is proven to descend from George Calvert, first Lord. We have for this part of the project, attempted to use the Harris(s)son Alias descendants of John Calvert, b 1692, son of George 1668. Even so, George is accepted but unproven with primary source documents to be the son of William Calvert, Esq., PSOM, who drowned in the Wicomico River in 1682. Philip Calvert's remains were used to attempt to extract DNA. However the attempt was not successful.

Henry Harford's descent is another possibility: He was the illegitimate son of Frederick Calvert and the recipient of the largest settlement awarded to the various proprietary inheritors after the American Revolution. Thus far we have been unable to find such a descendant.

Charles Calvert Lizenby(sic) HMS Regiment of Foot was another possibility. Samples in this potential descent have proven negative.

Distinct DNA group Nordic/Quaker/Irish - one of the predominant groups of the research is Nordic, more commonly known as the "Quaker" Calverts. This descent is proven to John Calvert of Yorkshire(Mooresome, near Gisbrough). John married Grace in about 1699 and removed to county Armagh Ireland in or before 1617. His son Thomas is listed in Quaker records.

Keep in mind that the spelling of the Calvert surname took many forms. Genetic matches of dissimilar surnames are common. First check the project that matches your surname but keep this in mind when researching. If DNA result match into the Calvert project, then your genetic research is indicating "Calvert" and not the other spelling.

Use the appropriate project or both. You can register your results with the matched spelling group and then cross-list to another project if ancestry is unsure, or if research further back in time has not proven with primary source records the origin of the family line.

There are several other groupings that are of import in the Colonial era as well as after.

The Y-DNA testing etablishes a scientific means for proof of Family lineage in addition to existing documentation, primary or secondary. For those who have encountered a "Brick Wall" in tracing family ancestry, the DNA study provides a means of linking such a Surname study to an existing or known line of Calverts via matching DNA. Indeed, as this project started, 5 results matched that were unexpected.


Establish - DNA homesite for Genealogical accounting of Calvert DNA which is intended to be public.

Provide - Assistance to Calvert (sic) Family researchers in proving family connections and ancestry for Today's Research and for those of the future.

It is the intent of those who began this study for it to continue. Coordinators will of course change, but the building of a Data Repository for Calvert DNA may be extremely Beneficial to those researching Family Ancestry, but also it may prove invaluable to Historians.

The Y-chromosome signatures change very slowly over time and the pattern is usually stable over hundreds of years, but for some unknown and unexpected reason, a mutation can occur without notice in any generation. Male relatives who have an uninterrupted male-male link between them will share the same, or very similar Y-chromosome. The mutation will show a deviance in a particular Marker. That deviance, in the category of a highly volatile marker makes matching DNA with exact matching markers impossible in some cases but does not indicate, for example in a 25 marker test a deviance which is not acceptable even if two markers are different.
