I am a descendant of Lucretia Shaw Hymas (b1822, d1873) who married George Adams at Tottenham (presumably England). My information is that Lucretia Hymas and George Adams had 10 children - Julia Elizabeth (b1846, d1929), Jeanetta Sarah (b1848, d1929), Frederick George (b1849, d1849 aged 1 day), Frederick George (b1851, d?), Lois Priscilla (b1852), Leo John (b1854, d1936), Owen James (b1856, d?), Frank Owen (b1857, d?), Marion Lucretia (b1859, d1941) and Marcus George (b1861, d?). Pricilla (b1817, d?), Frederick (b1818, d?) and Lucretia Shaw Hymas were the children of Stephen Hymas and Sarah (surname unknown). There ends my information on the Hymas line. Apparently Leo John Adams (married Elizabeth Barlow in 1885 at Opunake, New Zealand) and they had a son George (b1900, d1915, Hawera, New Zealand). I have more information on the George Adams/Lucretia Hymas descendents if required. This sounds like your tree as well - your contact back is welcomed!
