First of all there are no marriage records listed for this time period in Ludvika, so using the info I have found in several census records you can see when they were married on Nov 18 1842, they both were living at Klenshyttan in Ludvika when they were married. Here are four census records you can study info listed on Lars and Johanna.(OBS!,note that Johanna's birth date changes from Mar 22 1822 to Dec 22 1822 but it is the same person.GID: 156.24.1900,[Kopparberg]Ludvika,AI:5B, Husförhör, 1837 - 1847, 341/0,Bild 19 av 82, GID: 156.26.44900,[Kopparberg]Ludvika,AI:6B, Husförhör, 1848 - 1857, 351/0,Bild 146 av 199, GID: 156.29.42300,[Kopparberg]Ludvika,AI:7B, Husförhör, 1858 - 1864, 241/0,Bild 259 av 324, GID: 156.33.43700,[Kopparberg]Ludvika,AI:8A, Husförhör, 1864 - 1873, 357/0,Bild 267 av 286. You can see on Johanna's emigration record they have written her right birth date.
Secondly, on Ancestry you have posted a query about a daughter named Ingrid b 1849 to this same couple but if this is the same couple you can see they never had a daughter named Ingrid but in 1849 this couple had a son named Per Gustaf b Dec 7 1849, he emigrated to N. America 1869. Here is his emigration record found on the Emibas CD: Post 934732
