My name, at birth, was Robert Bryan GUTTMANN. My parents are both Ashkenazi Jews who were born in Germany and were living there in November 1938. They each escaped from Nazi Germany with a fragmented part of their family. Eventually they met and married in the United States, where I and my brother were born. Our sister was born in Brazil, where my father’s family settled.
I research our family history using traditional methods of records searching and analysis. I also conduct genetic genealogy research to match triangulated segments of atDNA with that of known relatives.
Families that I Research
Here is a list of family names that research: https://ferthalangur.spotch.com/genealogy/families/. Each entry there will eventually link to a specific page for that family group.
Published Family Trees
The most current and correct version of my research is stored locally on my computers in a genealogical database. This is also where my research notes, raw data, etc. are stored, with backups. The public versions (non-living individuals) are accessible on Ancestry and Geni.
Ancestry.COM Family Tree
Ancestry.COM is currently the place where I synchronize my database to the Internet. The site is named “Guttmann Rosenburg Koppel Sigman Families” and the URL is https://www.ancestry.com/family-tree/tree/118982676.
Access to non-living individuals is available to anybody who has a records research account on Ancestry.COM just by clicking on the link. If you do not have an Ancestry account, or if the link does not take you to my family tree, contact me and I will send you an invitation to view the tree for free. Include the email address and account userID that you have at Ancestry.
Living individuals are not shown by default. I will only provide access to living individuals if there is strong evidence that you are a family member, or at my discretion otherwise. If you are not a family member, please review my sharing policy. Non-family researchers will be granted access to living persons on a temporary basis, evaluated on a case-by-case basis.
To avoid confusion here … “confirmed as a family member” does not mean that one of the DNA matching services says that we are second or third cousins. I am afraid that puts you into a group of over 100,000 “relatives” and we will have to do better than that. My sharing policy intends to protect you and your family as much as my own.
Browsing and Matching a GEDCOM
I don’t provide a downloadable GEDCOM file online. Contact me if you have your family tree in a sharable (sanitized) GEDCOM format and would like to compare it to mine. My tree is a bit too large to eyeball, so it will be necessary to use some automated tools to find matching individuals. I can run this on my computer. There are also some online tools that might be useful for doing some matching. I would get your explicit permission before doing anything with your GEDCOM outside the security of my computers.
Geni : A Global Family Tree
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.
Geni is a global family tree site. Geni connects family trees together 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.
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 logged in, you can able to browse the tree, and click on links to individual profiles.
If you are a family member, please contact me after you have created a Geni profile so that we can link your profile into the world family tree, and invite you to the family group.
Please take care when using Geni as a data source. There are many connections that are unproven or even “wishful thinking” in some cases. If sources are not listed … beware. If sources are listed and those sources are other genealogies scraped off the Internet … beware.
My DNA Kits
I deleted all my public kits from GEDMatch in 2019. None of the kit numbers listed below should provide data on GEDMatch. If you downloaded and saved GEDMatch data before November 18, 2019, some of these kits might match your data:
|Kit ID||Whose Kit?|
|PM367889M1||my phased DNA (maternal)|
|PM367889P1||my phased DNA (paternal)|
The following kits were on GEDMatch Genesis.
|Kit ID||Whose kit?|
|UT3757008M1||my phased DNA (phased maternal)|
|UT3757008P1||my phased DNA (phased paternal)|
|SQ7350329M1||my sister (phased maternal)|
|SQ7350329P1||my sister (phased paternal)|
My brother’s DNA is not sequencable, unfortunately.
