If one accepts that Michael & Sarah Bowen nee’ Evans are the parents of Robert, Wm & John (you decide), then I believe Michael was baptized at St Ishmaels in 1837. If that’s correct then the IGI shows us 08 Jan 1837 Michael to George & Lettice Bowen baptized at St Ishmaels. In which case I believe George Bowen mrd Lettice Lewis at Hasguard 24 August 1830.
