In addition to the answers I publish on this site there are often other perfectly good questions which are handled by emails, because I can only give limited help.
Hannah is researching a house on the estate which was built between Sandridge Road, St Albans and St Saviour's Church in the 1881-1901 period. While I researched parts of this estate in my studies of Bernards Heath, I did not collect any information on the house in question although its location suggests it might have been built as a manager's house in connection with the nearby brickworks. Fortunately Hannah lives in St Albans so I was able to tell her that the St Albans Central Library has copies of old street directories on the open shelves from 1880 and she could probably find the answer to her question by looking through these.
Robert's ancestor, John Wheeler was born in about 1735 and lived in Harlington, Bedfordshire - but has drawn a blank when trying to find information on his birth in the Bedfordshire records. He wrote asking if a John Wheeler baptised at Berkhamsted St Peter in 1733 could be his man and I had to tell him that the Militia Lists and a will suggested he was a butcher who stayed in Berkhamsted.
Nicky is researching a house and while she has tracked down several old maps she has been able to find where there is a copy of the Tring Tithe Map from the 1840s. In theory there should be three but all seem to be "missing". Tim has provided some additional information relevant to the Tring Town Council records and if a copy turns up, preferably with the schedule, I will happily publish details on this site.
