Was the mother of Johan Eriksson (1727-1782) named Carin Granstrom?

Question

On Family Search they have the parents of Johan Eriksson ( https://www.familysearch.org/tree/person/details/K2YY-SMS ) listed as Erik Johansson ( https://www.familysearch.org/tree/person/details/MHZ1-QX5 ) and Carin Granstrom (https://www.familysearch.org/tree/person/KHFJ-65V).

Just want to double check as the parents of Carin Granstrom are listed as Johan Andersson and Malin.  

Carin Granstrom is listed as being born about 1705 in Gråträsk, Piteå Landsförsamling, Norrbotten, Sweden.  

Death about 1795, same location.

Just seems interesting to me as the Granstrom surname is found here about 90 years before my paternal great great grandfather chose it as his surname.  

Looks like at Geni she is listed as Kerstin Hansdotter.  Which could tie in with her fathers name of Johan, right?  https://www.geni.com/people/Kerstin-Hansdotter/6000000023855455804

Thanks in advance for your help!

After Feb 1st Riksarkivet SVAR will be free of charge. Then you should be able to follow up on this birth record:

For Johan Ersson, born - no, baptized - 11 August 1727 the mother is just in the book as hustru Kierstin. The father is named Erik Frigifven - I think it must be a soldier's name, so he may well be a Johansson. Very odd as a name, means "released" so maybe he was a returning POW.
