A wide variety of sources have been used
Direct communication -Verbal and in writing
Information directly told me by my parents, uncles and aunts, my grandmother Ada Pullen, and other distant cousins, especially the recently deceased Cicely Douglas
Certificates of birth marriage and death & Indices to birth marriage and death registers, Including Overseas
In England. in many cases it is unnecessary to order certificates, but these indices pin down the occurrence to a quarter and a district. I have death certificates for the Edwards who died in BC, Canada. I have also used online Indices for Manitoba and British Columbia, Canada, NSW, Australia, and the Italian Genealogical Groupís indices for New York.
I have used English , Welsh and Scottish Censuses. These are available from 1841-1911. I have also used 1911 Canadian Census, and US Censuses from 1870-1930.
In one or two cases limited information has been available from earlier English Censuses.
These have been useful in tracking people in between Censuses, though UK directories usually only list head of household. Canadian and NSW Australian Directories have been free of those limitations
In some cases original records, mostly indices or films. The majority of pre 1837 records use the IGI available of the Family search Website. These include births and marriages, but not many deaths. The more recent Recordsearch website has added to these. Many County FHS publish CDs or microfiche of these, and some are online/
These are useful in adding to oneís info.
Books are helpful, also Google Books http://books.google.com
Record Offices and more localised centres
I have visited Surrey History Centre, Berkshire RO, Huntingdonshire RO, The National Archives, the Society of Genealogists, Staines and Hyde Park Family History Centres, Stockport Library, Tameside Local Studies Centre
The National Probate Calendar
The majority of this is now online on the Ancestry website. A useful site, give exact date of death and sometimes location.
The Times Digital Archive and the Gales 19th Century Newspapers are available online. The New York Times and the Brooklyn Ea
