I know it has been years...again! I keep ending up back to this thread when on my Gorringe side. In the past few years i have found information and quite a few newspaper articles regarding what happened with George and Margaret, she had an affair whilst he was at sea and ran off with a married man (who left her whilst whilst she suffered with Tubercuosis in which he got imprisoned for abandoning). She shipped all the furniture to Newport in her new mans name and took 2 of the children and left several with a neighbour. Upon George arriving home he reported the incident and they got caught. This happened mid 1884 and James Rowden was born Oct 1885....very very possible he isnt Georges, im not sure what happened to their relationship straight after what had happened, but evidently George remarried in 1890...maybe they rekindled for a short time who knows! Hope you're well, maybe you have this information already.
