George Hinkley and Louisa Lake :Married April 13, 1854 Phillips, Maine

I am looking for info on my gg grandparents. George Russel Hinkley and Louisa Lake of Phillips, Maine. They were married in 1854 and divorced on Sept. 1861. Was wondering if anyone might have any info on why Louisa appeared to leave the sate and re-married (a couple times), but doesn't seem to have taken her children with her.Diana Merchant
