I can try to help. But when you say you found some names on the 1901 census, do you mean you found the family names within your family, or just found some people with the same surname. It would be best if you gave me at least your grandfathers name and we can work backwards
In the local paper recently I found a Pantony who died in the First World War. I copied it for you and also have a small photo of him copied from the Isle of Thanet Gazette.
SAD NEWS
For Broadstairs Wife
Pte Charles W Pantony, of the Queen's Royal West Surrey Regt., who was
reported missing after the attack at Loos on September 25th 1915, has now
officially been reported killed on that date.
Although close upon fourteen months after he had failed to answer roll call
on that Memorable day, his wife, who resides at 2 Wrotham Avenue,
Broadstairs had not given up hope of her husband still being alive.
Pte Pantony volunteered for the colours in September 1914 and proceeded to
the Western Front with his battalion in March of the same year. He was doing
duty for a considerable time as a sniper. Previous to enlisting, the gallant
soldier was employed by Mr J T May, of Broadstairs, as a painter and had a
wide circle of friends among whom he was much respected.
