How the OGSPI website works

Think of a surname then use the expanded alphabet below. This is an example of results clicking LO then LOGAN then 1891 census

LOGAN 1891 census 102b1 family 015   @ca.on.ontario_county_west. pickering_township division 1 page 003 film T6358 lds1465783
18 LOGAN William m 48 married - Ont Scotland Protestant storekeeper
    son of LOGAN James and wife MILNE Eliza
    LOGAN William 11 with parents Pickering Township 1851 census on245 page 009 line 17
    LOGAN William 19 with parents Pickering Township 1861 census on274 page 084 line 15
    LOGAN William 29 with parents Pickering Township 1871 census district 048a1 family 047
19 LOGAN {WHITNEY} Eliza Jane f 46 married wife Ont Ire Ont Protestant
    linked as maiden name WHITNEY Eliza Jane
    daughter of WHITNEY Paul Frederick and wife Elizabeth
    LOGAN William 38 and wife Eliza Jane 36 Pickering Township 1881 census district 132a1 family 0025

{ } symbols designate the maiden name for a married woman or widow. {?} means her maiden name isn't entered yet.
    comments and extra links show indented with a smaller font. County Township Microfilm Number are all clickable links.
Click on a surname like LOGAN or MILNE or WHITNEY to jump to a list of categories and locations for the surname
Click on a given name like Frederick to jump to WHITNEY~Fre... and a more detailed list of categories and locations for the person
Given name logic is 3 letter wild card so you catch Fred Freddy Fred'k Frederic Fredrick Fredrik with a single click.
Clickable given names work well when we have just one person or a couple on each text or spreadsheet input line.
Surname only searching is better for Queries and Obituaries that may just list a large family as Larry Curley and Moe, Tom Dick and Harry, Fred and Wilma, Barney and Betty.

When OGSPI has more than one entry with the same given name they all get pre-sorted and cross linked before uploading.
The ▲ arrow following LOGAN William scrolls up to a preceeding entry with LOGAN William.
The ▼ arrow following LOGAN William scrolls down to the next entry with LOGAN William.
arrows are very fast because they operate entirely inside the file that is already loaded and on your screen
