BEST-SHAW/Powell marriage and issue

[colinp]

DPB online records the marriage in 2020 of the heir apparent to the Best-Shaw baronetcy (E 1665) Joshua [Josh] John Kirkland BEST-SHAW, music producer, to Eleanor [Ellie] Grace POWELL.  His fb suggests they married on 31 July 2020

They have a daughter Ophelia Merryn BEST-SHAW b regd Q4/2023 NE SOMERSET m/m/n POWELL

In checking the above I came across a birth registration for Callum Alexander BEST-SHAW in Q4/2020 LAMBETH m/m/n BEST-SHAW.  Possibly a son for an unmarried female member of the baronetical family?
