The best sources in such cases are tax registers (mantalslängder). They show that a farmer Nils in Bogsten had a son Per in late 1744, and a farmer Nils in Stintorp had a daughter Kerstin they same year. A year later the son is missing in Bogsten, but Nils in Stintorp has a son-in-law Per.
Another good source is probate inventories. Kerstin Nilsdotter's from 1779 is accessible online. She died in 1778, aged 53, so she could be Nils Nilsson's daughter Kerstin, born January 1725 in Stintorp. The same inventory names Anders Olofsson in Bogsten as the uncle of Kerstin's children. Anders's wife was Anna Nilsdotter, born 1735 to Nils Bengtsson i Skärpinge. Nils in Skärpinge is registered for the last time with a son Per 1743, Nils i Bogsten appears with a son Per in 1744, so I assume this is the same person. Looking for earlier children to Nils Bengtsson i Skärpinge I found the son Per born February 25 1724. According to the birth register the child's aunts were daughters of Per i Skärpinge. Nils Bengtssons wife Anna Persdotter, born abt 1699, died in 1732 in Skärpinge and Nils remarried the following year, meaning Anna Nilsdotter was Per Nilsson's half sister. The second wife came from Bogsten which explains the move in 1744.
