Member Tree Searches - When Places don't match



By Geoffrey Slinker, Ancestry Employee

The place for an Event may not be found in the "place system". This leads to what are known as "normalization" issues.

Consider this normalization example where the user can enter any of these:

  • Glasgow, Barren, Kentucky
  • Glasgow, Barren County, Ky, USA
  • Glasgow, Barren Co, Ky, USA

All of those represent the same place. Therefore when the data is entered it is normalized into one representation.

  • Glasgow, Barren, Kentucky, USA

That is "normalizing". That way no matter which representation of the place you use it will convert to the normalized place and then any data that has that normalized value will be found in a search query.

https://www.ancestry.com/search/collections/1030/?name=_Slinker&birth=_Glasgow+Barren+Ky&birth_x=_1-0&count=50&name_x=psi_1



The system that normalizes the places may not know of a specific place. The place data is always growing and changing. So what happens when a place is not known?

Here is an example. Please note that at the time of publication of this blog that the places were as described. The system is constantly improving and this example may not be the same in the future.

https://www.ancestry.com/search/collections/1030/?name=John_Coleman&birth=1817-10-5&birth_x=0-0-0&count=50&name_x=psi_1


The thing to notice is the birth place, "Foxton, Cambridgeshire, England".

If you go to the result you see the place is "Foxton, Leicestershire, England".


The problem is that the Foxton in Leicestershire is not in the system.

This blog entry is not about how and why such problems exist, but how to work around them.

Suppose you search for someone born in Foxton, Leicestershire, England.

https://www.ancestry.com/search/collections/1030/?name=John_Coleman&birth=1817-10-5_foxton-leicestershire-england-united+kingdom_85073&birth_x=0-0-0_1-0&count=50&name_x=psi_1

The results are empty! No one was found! That just can't be, you know there are persons born in Foxton, Cambridgeshire, England!


Here is how you get around this in Public Member Tree searches. Move the place to the "Key Words".


Here are the results!



Now to share a little feature that until now I only knew about. You can prefix the keyword search with birth, marriage, death, or residence.

https://www.ancestry.com/search/collections/1030/?name=John_Coleman&birth=1817-10-5&birth_x=0-0-0_1-0&count=50&keyword=Birth+Foxton,+Leicestershire,+England&keyword_x=1&name_x=psi_1


By prefixing the key word with birth it found data where there was a birth event that had Foxton, Leicestershire, England as well.

Since the results shows John Coleman we can see he died in Market Harborough. So if I change this search to be for a death in Foxton, Leicestershire, England it should not find John Coleman because he did not die in Foxton, Leicestershire, England.

What makes a "Good Search" on Ancestry

What  makes a "Good Search" on Ancestry? by Geoffrey Slinker, Ancestry Employee The postings on this site are my own and do not reflect the views or opinions of Ancestry. The audience of this post is those that are new to searching, inexperienced, and those just learning.  If you have tried to find something and you didn't find what you are looking for have you considered: Do you know what you are looking for? Information of someone that is completely unknown, such as, I have no information about my great grandfather and I would like to find out his name. Information about someone that you know something about, such as, I know my great grandfather's name, but I don't know when he was born. Do you know where you are looking? What does this mean? Do you understand that when you are searching "Historical Records" you are looking for a "piece of paper" that has information on it matching your search? Are you searching for your ...

Searching for Persons in User Contributed Trees

By Geoffrey Slinker, Ancestry Employee The postings on this site are my own and do not reflect the views or opinions of Ancestry. Disclosure The purpose of this post is to give insights on how I use the new searching experience for member tree data, how I construct searches, and how I interpret the results. Maybe my explanations will help you find what you are looking for. Searching Public Member Trees https://www.ancestry.com/search/collections/pubmembertrees/ Ancestry recently changed public / private member tree searching. Be aware that you can only search for non-living persons. So, searching for yourself isn't expected to give results, and the same is true for any living relative or person. Person Centric Searching Even though the search is called "Public Member Trees" you are not searching for a tree. A member tree search would have fields for searching by a member's name or by a member's tree name. https://www.ancestry.com/search/collect...

Historical Places - Cities that Change Name

Historical Places - Cities that Change Name by Geoffrey Slinker, Ancestry Employee The postings on this site are my own and do not reflect the views or opinions of Ancestry. Locations change name over time. A city's name can change. A city's state can change. It is important to know this when searching for data on Ancestry.com. Renamed Places For example: North Carolina Hamburgh changed to Glenville. 1827 Hamburgh (later Hamburg) 1891 Glenville Hamburgh -vs- Glenville Let's try to find this record. If you were to type in the place of death, "Hamburgh, North Carolina", and you do not choose from the drop down "place picker", that is you type in the value and click outside of the typing area you would probably expect the search to find the record. However, there are no results. https://www.ancestry.com/search/?name=Hoty_Bowman&death=1916_Hamburgh-North+Carolina&count=50&death_x=0-0-0_1-0&name_x=s_...
