After completing my work with the hereditary peers, I've begun comparing my notes (based on DPB 2019, plus updates posted here) with DPB Online.
Some of the changes may or may not have already been posted here, and if they have, my apologies.
I've managed to get through the "A"'s and "B"'s, and will continue using this thread as I go along.
One last thing: unlike DPB, my list is alphabetical by the first name, so for example, "Aubrey-Fletcher" is listed with the A's and not the F's.
AUBREY-FLETCHER-- The 3rd son Harry, has 2 sons, Rafe Buchanan (b. 2015) and Jack Buchanan (b. 2017). Also, it should be noted that Harry's wife, and the boys' mother, Hon. Sarah (nee Stourton) is the sister of Lord Mowbray, Segrave and Stourton. She is the eldest of his 4 sisters who are co-heiresses presumptive to the baronies of Mowbray and Segrave, so these boys are also in the line of succession to those titles as well.
BERNEY-- The son and ha, WILLIAM, has a son, Thomas (b. 2018)
BOLES-- The son and ha, JAMES, has a son, Ronnie Thomas J.F.. (b. 2016). He was born the same year as his parents (wife/mother's name is Brenny Sally Blake) were married, so further research needs to be done to see if he is in remainder.
BORTHWICK -- The son and ha, MATTHEW, has a son, Henry Thomas R. (b. 2014)
BOUGHEY-- There is a new ha, as the current baronet has a son, ALEXANDER MICHELOF (b. 2010).
BOWYER-- Thomas, the only son of the hp JOHN JEREMY WINDHAM, has a son, Alistair Ashe (b. 2020)
BROOKSBANK-- The son and ha, FLORIAN, has a son, Oliver Stamp (b. 2015). This situation is exactly like the Boles case, as Florian and his wife Tiffany-Rose, da of Russell Lawson of Invercargill, NZ, were married in 2015. Further research needs to be done. as to whether or not Oliver is in the line of succession.
BRUCE (1628)-- It looks like DPB Online has taken to calling those baronets whose names are not on the Official Roll of the Baronetage "de jure." (I believe this is the first time I have encountered that with DPB Online.) With the current baronet, Michael Ian Richard BRUCE not on the official list, he is listed as "de jure 13th Baronet" and the baronetage is listed as "Dormant 2021.) The brother and hp ROBERT DUDLEY, had adopted the surname of his stepfather, which I believe was "ROSS." In 2018, Robert legally changed it back to "BRUCE." However, according to DPB Online, his 2 sons Zachary Scott (b. 1991) and Skyler Michael (b. 1993) are still going by the surname "ROSS."
BUCKWORYH-HERNE-SOAME-- Similar to BRUCE, the baronetage is listed as "Dormant 2013", and the current baronet, Richard, as the "de jure 13th Baronet."
BURBIDGE-- Similar to BRUCE, the baronetage is listed as "Dormant 2019" , and the current baronet, John, as the "de jure 7th baronet."
BUXTON-- The current baronet's son, Milo (born the same year as his parents' marriage, 2005) is no longer shown as ha. First in the line of succession is a great-grandson of the 4th Baronet (by way of his son Clarence and grandson Rupert) JONATHAN (b. 1950). JONATHAN has one son, Nicholas Rupert (b. 1982), shown as unmarried.
