Jon,
According to our manuscript family records, any connection that might exist will be very distant and possibly tenuous. Thomas who married Alice Ripper in Hanover Sq., London, had been living in Ipswich, as also seems likely had Alice (whose background is very obscure). He was the great great grandson of Charles Brady of Orford, who died 1757 and is believed to have been born around 1670. The ONLY John that we have recorded as related to our male line through Charles was not born until 1797, and he spent most of his life in the West Indies and as far as we know died childless. He was one of Thomas(=Alice)’s brothers.
Any relationship to your John & Sarah that might possibly exist is likely to have been through Charles’s cousin Robert whose family were a noticeable presence in the Orford Area during the XVIII century, farming at Iken Hall and then Chillesford; however, no John is mentioned. Robert had a son and grandson both called William, and the latter had a son Robert, who is stated as being the last of that male line, dying childless in the early 1800s (date un-cipherable). My family through Charles and Robert’s family were close, standing godfather to children etc., and there should therefore have been good knowledge of any other males, including a John.
However, do not assume that Robert’s line is the only possibility from which your John emerged. The chronicler of our family archive wrote in 1840: “There is a reduced family at Ipswich, from Norfolk, but in no degree connected with us. It is solely in the Huntley - Orford family that I am interested, and of that family the only males alive within my knowledge are myself, three brothers and six sons of two of them” (he is assuming that by then Robert’s family had died out). This said, there is the clear documentary evidence of other Bradys in poor circumstances and our family chronicler must have been aware of them in a small town like Orford.
Then there is the question of the John Brady who was born in Orford in 1652 and still around in 1699. Was he a progenitor of Charles and/or Robert; did he head a third line Registry records in Orford and surrounds seem to have been very badly kept...a point already recognised by our chronicler and referred to back in 1840! Note, please, that very little of the above is currently backed up by independent records.
