Father Patrick Comerford has done a lot of research into the Comerford surname, registering it at the Guild of One Name Studies and posting his findings on his blog. He has cut through a lot of the unsubstantiated older family history and has pinpointed two origins for the name and its variants - Comberford in Staffordshire and Quemerford in Wiltshire near Calne.
The Irish Comerfords largely descend from the latter, usually first appearing in the records as de Quemerford, stabilising as Comerford in the 16th Century. They look to have arrived from England in the late 13th Century/early 14th Century when William de Calne married into a prestigious Irish family. William had a number of English lawyers and agents look after his affairs, including a Philip de Quemerford/ (sometimes Philip of Cummerford) who settled in Kilkenny. The de Quemerford family had faded away in Wiltshire by the end of the 14th Century. The family are then found working in Ireland over the next century or two as lawyers or agents managing estates in Ireland, as well as local worthies.
Father Patrick has identified eleven branches of the Comerford family, but tracing them down to the present day can be difficult. The aim of this project is to bring together all the Comerford, Comberford and Quemerford (and variations like Commerford, Cummerford, Cumiford, Compfort, Comport and Comfort). This will should us to tease out the more recent Comerford lines, which combined with DNA, could help group them by their deeper ancestry.

Father Patrick has gone into depth on the Comerford coats of arms, which has varied across the years and branches of the families.
The earliest one, on the tomb of Gerald Comerford d. 1604, has the blazon "Azure, a bugle horn Argent stringed Gules, between three mullets Or" and this is the one used for the project (with the five points, although the photograph shows pierced eight pointed stars). Later coats of arms incorporated the Comberford, Staffordshire coat of arms in the mistaken belief that this was the origin of the Irish Comerfords. The most popular version of this is a quartered shield with the Comberford arms, "Gules, a talbot passant Argent", in the top left and bottom right, alongside the Comerford arms in the other two corners.
Comerford coat of arms used here was created using Uplink Heraldry Generator.
There are a number of DNA projects at FTNDA that Comerfords could join:
