Genealogy and Genetics are not the same thing. Genealogist are family historians and therefore they discover people's ancestry. If a person has a genetics question they should go under Science and Mathematics and the sub category Biology but we get Genetics question here and it annoys some of the regulars.,.

You might say Genealogy is researching one's ancestry using documents/records.

Ancestry.Com has a lot of records. Now you have to distinguish between the records they have and their subscriber submitted family trees which should be verified with records. Even when you see the absolute same information on the same people from many different subscribers, as unfortunately, too many people copy without verifying. No, the websites do not hire people to verify the information their subscribers submit. It would be far too costly. Any photos will in subscriber submitted family trees.

With some records they have a image of the original document and somtimes it is only on an index, but when it is only on an index then you have an idea as to what courthouse etc to write to get a copy of the original and that is a lot less costly than traveling great distances to get it.

A lot of public libraries have a subscription to Ancesty.Com you can use for free. Also FamilySearch.org is entirely free. I believe each of those 2 websites have more records online than all of the others put together. Still with FamilySearch.org don t take as fact what you see in their subscriber submitted family trees.

It doesn't matter where it "originates" from it tells you zero about your ancestors.
Surnames are words they come from language heard, spoken or which influenced people, so someone with a Spanish language word name, could have originated from Peru or Mexico or Argentina or many other countries and they nor any of their ancestors ever set foot in Spain...so word history is not genealogy research

The ONLY way to find out who your ancestors were is to research the written records each and every one of them generated during their lifetime, those tll you who they were, where they came from regardless of the word they used as a name

Where is the birth time located on a german birth certificate in 1948, Stuttgart Germany.

There is a number on the upper right hand corner 6100/1948. The person was born in 1948, but I don't understand what the 6100 means. The entire birth date is recorded on the bottom of the page, but there is no time of birth that I can make out.

What I did, since I don't know my biological father's ethnicity, is take the AncestryDNA test, but my approach was to use the process of elimination by basing my conclusion on matches...

Since I'm Asian, though, I got a lot of matches of different Asian races, so that might happen with you, too.

The 1918 Wilmington, Delaware city directory lists his wife as Anna:
Spinazzola, Angelo (Anna), barber, h. 122 Cedar

In 1917, she's Annie E.
Spinazzola, Angelo (Annie E), barber, 219 Md ave, h. 118 Cedar

Rita's social security application lists her mother as Anna Gladkowski:

The social security application for Rita's brother (Michaelangelo Jr., born 1917) also lists mother as Anna Gladkowski. So does the death certificate for their brother Edward (born 1916, died 1919).

Why do you believe that Anna/Hannah was his 2nd wife and not the mother of Rita?
