wikipedia states that the supposed 8th Bt is Fernando "Nascienceno" Poore b 1964. They seem to have taken the spelling of the middle name from
thepeerage.com which cites peeragenews.blogspot. Fernando did not appear in the last Burke's P&B but in Debrett's his middle name is "Nasionceno" which seems consistent with the spelling of the name by other members of the family
wikipedia then goes on to say that the heir apparent is Fernando's son Roberto. He however does not appear in Debrett's which states that Fernando has a son Juan Ignacio b 1985. It is uncertain whether he is in remainder as the date of Fernando's marriage to Maria del Carmen is not given
In Debrett's Fernando is indicated as the heir presumptive. His birth year is the same as his parent's marriage year but one assumes Debrett's will have checked that Fernando's birth postdates the marriage.
DPB online states that Sir Roger Ricardo Poore succ "1900" but this should be "c 2004" or "by 2004" as per the last print edition. DPB online also states Sir Roger m his brother's wife "1900" - again this an error for "19-" as per the print edition
The SCB website states the 6th Baronet died "c 2004" but Sir Roger, the putative 7th Bt has never proved his claim.
