My Family History

My name, at birth, was Robert Bryan GUTTMANN. My parents are both Ashkenazi Jews who were born in Germany, escaped from the Nazi regime and fled to South America. Eventually they both ended up in the United States, in New York City, where I was born.

All of the ancestry that I have traced so far is Ashkenazi Jewish, mostly from Germany and German-speaking regions of what is now Poland. DNA testing confirms this. I and my brother are the first generation of our family born in the United States, with the exception of our great-grandfather, William ROSENBURG, who was born in 1856 in Baltimore, Maryland in 1856. He then moved back to Karlsruhe, Germany, married and raised his family there.

All other ancestors that we have traced so far are from Germany, or German-speaking Poland.

My Published Family Trees

There are several ways that you can access my family tree, trees that feed into it, and in some cases related trees that have some connection to it.

Ancestry.COM : Guttmann Rosenburg Koppel Sigmann Families

This is the most up-to-date published copy of my family tree. I keep this tree synchronized within a few days with my working research database on my computer.

https://www.ancestry.com/family-tree/tree/118982676

If you have a records research account on Ancestry.com you should be able to follow the link by clicking on it. If you do not have an Ancestry account, or the link does not take you to my family tree, contact me (include your email address in the form) and I will send you an invitation to view the tree for free. You will need to create a username and password on Ancestry, but you will be able to view my tree (or any other that you are invited to) for free.

Living individuals are not shown by default. In general, I will only provide access to living individuals if you are confirmed as a family member. If you are not a family member, please review my sharing policy. Non-family will be granted access to living persons on a temporary case-by-case basis.

GEDMatch : GEDCOM file

I don’t have a downloadable GEDCOM file available online. Contact me if you have your family tree in a GEDCOM format and would like to compare it to mine. There are some tools available for comparing GEDCOMs.

A sanitized GEDCOM file of my research is uploaded to GEDMatch and you may compare your GEDCOM or others that are loaded to GEDMatch. The GEDCOM ID is 2349793.

You can browse the GEDCOM by clicking on this link. Living persons are hidden, but you can click on the Pedigree box to see my ancestors and navigate the GEDCOM that way. This does not get updated as often as the tree on Ancestry.

You will need to create a username and password to use the tools on GEDMatch.

Geni : A Global Family Tree

Geni is a global family tree site. Instead of a site where each user has their own personal family tree, Geni connects family trees with matching individuals into one interlinked tree. Individual genealogists collaborate to merge individuals and reconcile conflicting information. Geni has a very broad reach and is curated by a cadre of volunteer genealogists.

My profile on Geni is Robert Bryan Jenson né Guttmann. In the family research pages linked here, you will see hyperlinks from individual names to their Geni profile.

To access data on Geni, you will need to create a free account and log in to browse the tree. You can skip entering all the information about your family until you are ready to connect yourself to the tree. Once you have a Geni account and you have logged in, you will be able to browse the tree, and click on links to individual profiles.
