Thank you for digging this will up. Bill was the son of Samuel Coombes (he took the e out) and Samuel was the son of another William Coombes born 1700 (can't find anything beyond him). Bill Coombs was father of Robert Smith Coombs who went to India and family stayed there for 5 generations. I'm of that line so pleased to learn about Hog Lane! Woolwich obviously where Robert sailed from, but with East India Company back then. Cheers, Alistair
ps Bill was 1749 - 1793 from what I can see so don't know what the 18 signifies on will.
