Welcome to the One-Name Study web pages for all HARTRUM and HOTRUM families.
The HARTRUM / HOTRUM Family Tree pages linked to this page are a compilation of the work of many researchers documenting their ancestry.  If you have any HARTRUMs or HOTRUMs in your ancestry then this web site is also yours and we would appreciate hearing from you.  We hope you will benefit from the information provided here and will share your findings (and any disagreements) with us.  All information about living individuals is kept in the strictest confidence.

My name is David Naylor and I am the compiler of this family tree.  I live in Canada and am retired from designing computer systems for the telecommunications industry.  I've been interested in genealogy and researching my own family tree since I was presented with my family's Naylor Family Bible in 1950 following the death of my paternal Grandmother, as I was the last known male expected to continue this Naylor lineage.  The amount of time spent researching has greatly increased since retiring from gainful employment and this has helped to keep me entertained and out of trouble. 

While researching my wife's HOTRUM roots I realized that all HOTRUM and HARTRUM families were likely related.  I found this very interesting and therefore decided to research them all.  Except for a few occurrences of the HARTRUM name in London, England in the 1600s, they seem unique to North America.  This research put me in contact with others researching these same names and they have kindly provided their data for inclusion in this One-Name Study database.

In New Jersey and Ontario of the late 1700s and early 1800s the same individuals appear with different spelling of their surname — HADERIM, HARDRAM, HARTRAM, HARTRUM, HATRAM, HATRUM, HATTERIM, HOTHERHAM, HOTRUM, HOTRAM, etc.  Since many people of that day could not spell or write, their names were written as the writer heard them and as these were Germanic-speaking folks with harsh pronunciation their names ended up every-which-way.  Because these names have not been located in Europe some researchers believe that they may have been derived from some other more-common surname — suggestions for this have been HARTRANFT, HARTRUMPH, and HARTMANN.  However, the earliest spellings and also family stories indicate that the name was pronounced with 3 syllables and those suggested names are all only 2 syllables.

Searches of ships' passenger lists for these names have not been very fruitful.  The most interesting candidates, so far, are:

Research emphasis is currently in New Jersey, USA where the earliest-known individual, "Joh: HARDRAM", was buried at Zion Lutheran Church in what was New Germantown (now Oldwick) Hunterdon County on 30 August 1784 at the age of 62.  Much more data is needed from this area to prove the linkages of the early family members and to trace their roots back to Europe.

We believe that one or two families of Hartrums moved within New Jersey from Hunterdon County to an area overlapping the border between Morris and Bergen (now Passaic) Counties in the late 1700s.  Edward and George, and their families are found in the 1830 census in Pompton Township, Bergen County (we believe they lived near Newfoundland).  In the mid-1830s these families moved to Ohio.  Also moving to Ohio at about this same time was the family of Frederick Hartrum.  The descendants of these three families are still mainly in Ohio, with one branch in Chicago, Illinois.  Recently, within the last one or two generations, some Hunterdon County families descending from John A. Hartrum, changed the spelling of their surname to HARTRIM.  Descendants of all these HARTRUM families are found today across the USA.  Still more Hunterdon County families, these ones descending from John J. "Alex" Hartrum, changed the spelling of their surname to HARTMAN.  They are still mainly in New Jersey but are lost amongst the other Hartmans.  Perhaps these last two name changes were made because the families didn't like RUM!☺   We have not yet proven that all these families are connected but hope to do so using DNA testing.

From Morris County, New Jersey, one family (Conrad, wife Catharina and children) moved to Upper Canada (now Ontario,Canada) in 1793.  The spelling of this family's surname became fixed as HOTRUM.  Today there are hundreds of their descendants living in Canada and the USA.  Some descendants of this family moved to Michigan, USA around 1860.  They were the ancestors of all of the HOTRUMs now living in south-west Michigan and Washington state.

We are now using DNA testing to help discover the original ancestral surname, to verify that the family tree as we have it is correct, and to see if the various unconnected branches of HARTRUM and HOTRUM families have common ancestors.  For this purpose we need male individuals with the HARTRUM, HARTRIM or HOTRUM surname (and even a BRONSON) to supply a DNA sample (by means of a mouth swab) for Y-DNA testing.  Other descendants, of either gender, are also welcomed to take an autosomal-DNA test to see which family connections show up.  All tested individuals will get their results which will show their connection to other individuals around the world (that have also been tested).  Go to our DNA page for further information.
