• David was from Wales.  His birth date (10 August 1821) was recorded on the day he received a Patriarchal Blessing (3 February 1860) at Spanish Fork, Utah.  This record may be found in the Early Church Information File at the Church History Library in Salt Lake City and corresponds closely with the birth year recorded in the 15 December 1856 Journal History.  His tombstone gives a birth date of 10 August 1819 which appears to be incorrect.
