Hi Keith,
Just a thought, have you got the printout of the 1901 census, with your ancestor on - the reason I am asking is, because if there are any other roads mentioned on
the same page, apart from Seaside, it might give another clue - as I was driving along seaside this morning, I noticed a row of old terraced type houses, which could be classed as cottages, next to Myrtle Road - Haven't got round to asking them at work yet, as the phone didn't stop ringing - hopefully 2moro.
Maybe a bit of a longshot, but worth asking.
best wishes
Sandra
