Thomas Phillips, a lead miner born about 1819 in St Mewan, and his wife Mary Harvey had 3 children. The parents appear to have died before the 1861 census as the children are living with relations; James and Thomas with their uncle Stephen Phillips and family in Menheniot and Ellen Jane is with her aunt Caroline Martin, maiden surname Phillips, and her grandmother Catherine Phillips in Liskeard.
James Phillips married Catherine Bunney in Redruth in 1866 and by the birth of second child William they are in Loudoun near Galston in Ayrshire, In the 1881 census they are back in St Stephen in Brannel but it seems to have been only a short stay as son John was born in 1880 in Galston and son James in 1882.
I can't place Ellen Jane Phillips in the 1871 census but she married Cornishman Arthur Burley in Loudoun in July 1872. In the 1890s they moved from Loudoun parish to Cumnock. Arthur died in 1915 in Galston and Ellen in 1927 in nearby Newmilns.
Thomas Henry Phillips married Louisa Trudgian in 1870 in Loudoun and was living next door to his brother James in Loudoun Rows in 1871. They were back to St Stephen in Brannel by 1879 and stayed in Cornwall.
