here it is, online as a .pdf (commentary and full set of slides).
Had about thirty people listening, folks taking my business card to ask future questions. I never mind helping researchers among the family history / genealogy community to get over a hurdle or two. After all, I've have help from fellow researchers in the past. If things involve a fair bit of time, though, I do have to charge.
Next big presentation is in June, on Henderson's Mill before members of the West Auckland Historical Society, then another in August, back at Central Library on medical records.
No time to get bored around here ...
