Lennan (and variants): Dublin data index

As noted previously, the L*nn*n data indexed below has been extracted from diverse sources, but principally the GRO births, marriages and deaths index and certificates. It should be stressed that the data may be partial, and transcription errors may exist. Also, the concentration of research was on Dublin Lenn*ns. Given the alphabet, Lann*n and Linn*n may generally have been missed in recording. Other variants such as Lenehan, are generally not recorded, nor are Lennons etc. outside the greater Dublin area (including Rathdown). Given, these disclaimers, data, representing over 9400 (in September 2002) events, are quite comprehensive. An analysis of the data is contained in "The Dublin data: some comments" on page 6. For confidentiality purposes, 2100 entries of possible living people have been excluded (birth events being included in the data to 1900, marriages to 1920 and deaths to 1980). Birth events to 1974, deaths to 1990 and marriages to 1975, are available in my unpublished data. Look-ups can be carried out in this supplementary data for L*nn*n researchers on specific request. As additional certificates are purchased (generally in tens - resulting in, at most thirty entries), these will first be included in an 'extras' category. Subsequently they will be integrated in the sorted data.

Automatic conversion of excel data had resulted in very large html files (many around 1Mega per page, with 'J' and 'M' even requiring two pages). Things were improved by a factor of 5 by using Hot Metal Pro generated code rather than that produced by Excel. With the possible exception of the 'J' and 'M' pages, both just above 500k, html viewing is now feasible. But the optimal recommendation is still to download the pdf files which are now 'only' 4 times smaller (as opposed to 20 times previously). It should also be noted that the html tables take additional time to format (so you may be at 91% loaded for several minutes on large pages!). The pdf files have the additional benefit of being updated more frequently. One slight downside is that longer entries may be truncated. If you do not already have the Acrobat Reader for reading pdf. files, the most recent version can be downloaded free from the Acrobat site (unfortunately a fairly hefty 8.6M download, but it is also widely available on computer magazine CD-Roms).

KEY TO DATA FILES

Content of columns in data

1. Reference No.
2. Event: b=birth, m=marriage, d=death, l=living(presumed), ad=already dead, u=unknown;
3. Christian Name;
4. Surname variant: a=Lennan, o=Lennon, nan=Lenan etc.;
5. Year;
6. Quarter;
7. Date;
8. Area (narrow) or church, CoI=Church of Ireland;
9. Area (wide);
10. Sex, u=unknown (a few m/f errors appear here and there);
11. Second principal (sometimes inverted i.e. f: usually father of, but early numbers could be father to, also w: can be wife but, sometimes, witness - but most instances corrected in March 2000 data). Numbers refer to another entry for same event in column 1. Most events have around three entries - thus a birth would have a Lennan child, mother and father, a death will usually have one or two (a Lennan witness), a marriage of a Lennan male usually three (husband, wife and father of husband) but sometimes Lennan witnesses, etc., sis=sister, br=brother.;
12. Third principal or other descriptive such as occupation, area or maiden name (sometimes m or, more regularly n). A no. refers to an event of the ID in the first column;
13. Age;
14. Additional information (derived=a birth derived from age given at marriage or death);
15. Basic source: most common is r=GRO data, others are con=convict, dd or ods=Dublin directories, Eliz=Elizabethan pardons, g=grave, gv=Griffith's Valuation, IGI=International Genealogical Index, ml=marriage licence, pr=parish record (DLRHC being Dun Laoghaire/Rathdown Heritage Centre purchased data, DHC being Dublin Heritage Centre), vis=visitation, w=will;
16. Extra on source (e.g. Page in IGI, or reference for GRO - where 2393 would be Volume 2 Page No. 393 and 12548 would be Volume 12 page 548; cert=information from photocopy of GRO entry);
17. Address: Street No.;
18. Address: Street;
19. Maiden name associated with the event. For father at birth, wife's maiden name usually included.
