I'm french, and it's difficult for me 
I found my ancestor: Andreas Wennerstrom, but I don't understand who his parents are? In fact, I do not understand how to read this document. Can you help me? Could you explain to me the differents informations ?
Thanks for everything.
Have a nice day.

Farmhand Erik Larsson Wennergrens and wife Gunla Mobergs child Andreas, and after that the witnesses.

[Ingrid Gaquiere]

Thanks. So perhaps he isn't my ancestor; because his name was Wennerstrom and not Wennegrens  :'(

[Staffan Bergh]

This is the birth notice for a boy named Andreas -- with father Erich Larsson Wennergren, mother Gunla Moberg. One of the witnesses is a "sämskemakare" (chamois leather maker) called Wennström -- not quite "Wennerström" ...

How did you reach this notice (from your Gustaf Adolf born in Arboga, I presume?). And where is it?

[Ingrid Gaquiere]

Hello,

Thanks for your answer.

I found my ancestor Anders Gustav born in Alingsas 02/12/1820. I found his parents : Wennerstrom Anders born in Vanersborg 01/01/1779, and Lenberg Cathrina born in Hemsjo (1779).
So i searched in Vanerborf at the date...

I do not speak a word of Swedish, for English I have a school level, I must admit that it is very difficult for me to work on Swedish archives. You have a lot of information, and I'm discovering!

OK, this is your track to Andreas b 1779-07-01 in Vänersborg:

Gustav Adolf W. born 1891 in Eskilstuna <- Gustav Adolf W., born 1853 in Arboga <- Anders Gustav W. born 1820 in Alingsås: father Anders Wennerström.

AW  is consistently noted with birthdate 1779-07-01 in Vänersborg. The earliest I find him is 1812, probably, in Falköping. He's a journeyman shoemaker, and given that he hasn't made master in spite of being 33 years old, he either wasn't a very good shoemaker, or he had problems with settling down ... He may have left Vänersborg  already 1795 or so, so it will be very hard to prove that he is (or is not) Erik Larsson Wennergrens son.

My anders Wennerstrom (Vennerstrom) married in Alingsas with Lenberg (Lenbherg) AnnaCatharina on September 10, 1820. I found this:
 

[Kalle Birgersson]

Since the date is spot on it must be the right birth note even if the father's last name isn't right. I just can't find any proof for it.
 
Erich Larsson Wennergren and Gunla Moberg married May 9 1779, less than two month before Andreas was born. Erich worked at a brewery.

They also got the daughter Sara Caisa November 2 1781. Erich was now a carpenter.

During all of this Erich's name is consistently Wennergren so it can't be just an error when Andreas was born. But where did they go after this? I can't find them any more, but lets keep looking.

[Kalle Birgersson]

But here is another clue, Sara dies at 4 years of age, February 17 1785. Now the parents are called just Erich Larsson and Gunla Israelsdotter.

And after another look, Gunla Israelsdotter also dies that year, January 17, two notes above. So, what happends with Erich now? He doesn't remarry, at least not in Vänersborg.

[Ingrid Gaquiere]

Thank you so much for the time you spend helping me!

Is it possible that Anders was "adopted" by the person who witnessed "venn strom" at birth? If his mother died when he was little?

[Kalle Birgersson]

No, adoption is unlikly at that time in history. Last name was not very static though, you just walked up to the priest and told him what your new last name was. People often took last names from their place of birth, in this case both Wennerström and Wennergren from the city of Vänersborg, as you can see they start with the same sounds.
 
Andreas was only 6 years old when his mother died. Maybe his father couldn't take care of him, so he was placed in a fosterhome and they lost touch with each other? Almost like adoption but not quite. Or maybe Andreas got mad at hes father for some reason and chose another last name?

[Per Sundin]

There is little problem with the difference in family names. There are numerous cases where young men in Sweden later changed the family name they were given by birth. But if you still have some doubt the names of his parents (Eric and Gunilla) at least in older times also were given to Anders own children. Of course, his origin could be solved with absolute certainty with the help of DNA.
