Please send any queries or pedigrees for this project to: brad.lnrd At gmail.com
We will list all families by earliest ancestor and line leader who wish to be listed. We hope that, eventually, all Leonard family lineages and major branches will be listed on this page. We also hope to locate descendants of each family lineage and branch and to arrange their participation in the DNA project. Participation in the Y-DNA Project is strongly suggested for listing on this page because we are trying to link Leonard lineages and branches back to haplogroups and marker patterns to aid others in their genealogical research.
Note that not all Leonards are related, at least within the past 600 years (they may have been 20,000 years ago, but we won't count that!). They tend to fall into clusters in various haplogroups.
Leonard pedigrees are arranged by haplogroup below. Individual descendants are tied to the Leonard surname table by the red L-numbers so that you can review their Y-STR patterns to see where you might fit.
Haplogroup J2a4h1 (J-L24) – Descendants of James Leonard b. 1620, Pontypool, Wales, d. 1691 Taunton, MA. Descendants of James' brother Henry also test in this haplogroup. Descendants of John Leonard of Springfield (1610-1676) may also be in this haplogroup.

Please note that these brief pedigrees do not include marriage information, any death information, or any details on the wife. It is intended to allow a researcher to identify a family of interest and then to contact the person to whom the pedigree belongs. It is NOT intended to provide all of the information that is known on this branch of the family, only a minimal amount to aid in linking the haplogroup lineage and the family branch with the marker patterns on the surname page. Sometimes, something more is listed on the first generation to aid in his identification, as usually little is known about him.
This is a work in progress! I’m trying to standardize the listings to include only man’s name, date and place of birth and death, and wife’s name, per general FamilyTreeDNA instructions. I’m also trying to obtain more of these brief pedigrees of our surname group’s members and would like your assistance. In some cases, the y-dna testing has been done elsewhere, and I am trying to obtain those results to tie this page to the y-dna results page.
The most common error in Leonard genealogical research is to assume that the person with the same given name as the one you're looking for is, indeed, the one you're looking for. Leonards with the same given names proliferate! Even after 1775, when two given names came into use, Leonards with identical names, such as John Henry Leonard or George Washington Leonard, are frequent.
Note that haplogroups are determined by mutations in SNP's. These occur more rarely than mutations in STR's. Therefore, y-str mutation patterns are more useful in determining branches within a family line, while SNP's are more useful in dtermining subclades of haplogroups. Work is proceeding at a fairly rapid clip in the sequencing of SNP's, that is, the order in which mutations in SNP's occurred over time. This means that while the mutations that, in effect, created what we call the J haplogroup occurred roughly 10,000 years ago, the further definition of subclades, such as J2, then J2a, then J2a1, then J2a1h, and so forth, moves us from the distant past to nearer present time and, hopefully, to identifying where your "deep" ancestors may have lived at that time. So you may want to check in with the project focussed on your haplogroup to see where progress now stands.
Warning: as further subclades are identified through the sequencing over time of mutations, so does their nomenclature change. So rather than J2a4h1a..., the notation becomes J-L24, named after the point down the sequence at which the mutation occurred. That mutation would have occurred about 2,000 years ago somewhere along the Mediterranean coast, perhaps in present day Turkey. If you find this confusing and mindboggling, well, it is confusing and mindboggling. But it seems to be the price of progress.
The major Leonard lines, named after their progenitors (first of the line to appear in the US) appear to be as follows:
John Leonard of Springfield, Massachusetts, arrived in the 1630's and settled in Springfield, MA. I have an extensive genealogy of his descendants.
Solomon Leonard of Duxbury, Massachusetts, arrived also in the 1630's, settling initially in Duxbury and soon moving to nearby Bridgewater, Massachusetts. His wife was a Mayflower descendant, meaning that all the descendants of that couple are Mayflower descendants. I have an extensive data base of his descendants.
James Leonard, ironworker, of Taunton, Massachusetts, arrived in the 1640's and intially settled in Braintree and Saugus, Massachusetts. I have an extensive data base of his descendants.
Henry Leonard, ironworker, of Saugus and Rowley, Massachusetts, later moving to New Jersey. A number of his descendants went south to North Carolina and from there west and south. I have a data base of some of his descendants, but they have been more difficult to trace than the New England Leonards.
George Leonard of Westchester, PA, born about 1685, either in England or Switzerland, married Christian, last name unknown. Some of his descendants went to Virginia and North Carolina. I'm trying to build a data base of this line.
Valentine Leonhardt, b. 1718 in Germany, settled in North Carolina, and his descendants spread west. I want to build a data base of this line.
Joseph S. Leonard arrived in Pennsylvania from Ireland in the 1740''s or 1750's, with descendants also going to North Carolina before heading west. I've started a data base of this line to assist in untangling the various Leonard lines in North Carolina.
Robert Leonard and his brothers Thomas and Samuel arrived somewhere around 1750, origins either Scotch or Irish. Robert was a soldier in the British army in the 1750's, later joined the Revolutionaries in the Revolutionary War. One of the brothers went to North Carolina, and the other to Georgia. Bob Leonard has a data base on these Leonards.
And there are more... Ancestry.com has some 1700 emigrants surnamed Leonard arriving on our shores in its data base, so there are probably lots of Leonard lines yet to be documented. Many arrived from Ireland in the 1800's. So don't get discouraged. The odds are that you had ancestors -- almost everyone does. The odds are that you had a lot more of them than you could ever meet and have a conversation with at a party. So just keep plugging away!
