I wonder if the birth for Vera O MARTIN in 1906 registered at Rockley with parents given names of William J and Mary J would be another sister for Lucy/ie and Myra? #17800
As mentioned earlier, a copy or transcript of Clarence Albert WOOD's d.c. seems to me to be the sensible option, it should list Lucy and Clarence's sons as per the IM, and also give di47 further information to advance her quest, as it should also confirm Clarence's parents. A transcript would be quicker and cheaper and contain the same information as the "real deal".
PS, see reply #9 for the d o d, the ref number and the probate packet index
