About thirty years ago I was asked to participate in a local history project concerning the history of the Staines & West Drayton Railway, but the publisher sat on the resulting Ms. for over three decades. It seems that he now wishes to proceed, which presents a bit of a problem, insofar as family history has moved on since the 1980s. I have, in consequence, being trying to check our initial findings against various on-line resources which were not available when the original work was carried out, and have hit a “brick wall” in the case of Alexander Van Ransellar Thuey (1842-1902), a civil engineer, apparently of West Indian origin, who was heavily involved with the promotion, construction and opening of the railway during the 1880s. Sadly, he died in obscurity on Brighton Workhouse, but the “standard” family history sources reveal that he was born in Nassau in 1842, married Eliza Georgina Benson in 1877, and had eight children. The family lived in Stevenage, Notting Hill and, later, in 15 Sidney Road, Forest Gate, while Thuey's Office was given as Palace Chambers, Westminster. The problems relate to the West Indian connection: It is known that an Alexander Thuey emigrated from New York to the British West Indies, which offered greater opportunities for coloured people than the USA. It is tempting to conclude that this Alexander was the father of the engineer, but the two sets of records do not entirely add up. Alexander Thuey, a carpenter, married Phebe Van Rensellaer, and died in Nassau on 27 November 1861, aged 57, and he is buried in the Western Cemetery, Nassau. However, the online sources that I have consulted make no mention of a son called Alexander – so were there any links between the Thueys, or were there two separate familes living in Nassau at the same time?
