Given CB's stated interest in programming, I think Git advocate refers to GitLab / GitHub - a system involved in software programming.
DPB online shows CB as m. 2009 to Silvie ZAMAZALOVA - is this person male / female (/other)? Not looking to get into one of these debates again, but this news probably means that CB Bailey will have no male issue (in terms of peerage law).
On that basis we should look into other heirs; the next heirs appear to be:
1. Lancelot O B., b 1936 (resident in France?) - descended from 5th son of 1st Baron.
2. Antoine L G B., b 1965 - only son of 1.
3. Malcolm B. b 19-- eldest son of 2.
4. Owen B. b 19-- second son of 2.
There seem to be plenty of heirs following this, so I don't think the title is at risk, though with only a few heirs listed born in the 20th century probably means that up-to-date information is lacking.
