Yes that is my father in law and his mother. I have her death cert and my father in laws birth cert.
My father in law was told his dad died but when Eileen died I see there was a Manuel Celestino Da Maia leaving Southampton in 1938, so I think he came back to get his son and the grandparents said no.
I have not found a married certificate for Eileen or Manuel yet either. I did dna on my father in law through ftdna and my husband through Ancestry. I have found my father in laws grandparents and ggg grandparents. Now trying to find any close living relatives is hard in Portugal. Could also be in US and Canada as well.
