Hello Allan
I've just sent you a really long reply expressing my gratitude and delight in the two websites and the message didn't send! I'm not good at doing this but here we go again.
William Reveley TENCH (mother Elizabeth REAVELEY) was born in Winlaton, Co. Durham in 1848 (father Anthony). He married Margaret KELLET in Sunderland in 1871. From there: 1871 an unemployed florist and gardener in Darlington; 1881 a clerk in Mansfield, Nottinghamshire; moved on to Ipswich, Suffolk; 1891 a mechanical engineer and manager in Garston; 1901 a pier erection engineer in Elswick, Newcastle upon Tyne. Known in the family as a bridge builder-that would fit in with the firm you mentioned in Garston- and seems to have been abroad quite a lot. At least three sons became engineers: John Anthony was an associated member of mechanical engineers in India; Richard and James Renwick were engineers in Canada. Mary BELL was William's second wife (maybe that's why it has Mary BELL and WILKINSON on the Yorkshire bmds. Formerly, she was the housekeeper.
with grateful thanks
