There's one thing to be said for choosing to slow down and do that "exhaustive" search for a missing ancestor: you can take in far more of the scenery when you take the slow route.
It's a "stop and smell the roses" kind of search. When we look up our ancestors' records using current-day search provisions, with one click of a button, our search terms are instantly translated into possibilities. Better yet, we don't even have to perform that search; handy "hints" pop up unbidden to beguile us away to a possible record set (which, mostly, serves up the correct answer). But go page by page through that same record set, looking with our own non-AI eyes? That's putting the research brakes on, benefitting us with a more leisurely, up-close review of the bigger picture.
As I looked, this past weekend, for any signs of John Kelly's own baptism, I noticed a few details. For one thing, "FAN Club" surnames back in Fort Wayne, Indiana, where John settled after emigration, popped up with regularity in the parish records I researched. This included Denehy, maiden name of the second wife of suspected Kelly relative, Timothy.
In addition, recalling Irish baptismal traditions, I watched not only for Kelly baptisms, but for any baptism in which a Kelly was named as a sponsor. With several such appearances, I'm noting the families connected to those Kelly godparents, as possible guidance in piecing together a Kelly family tree back in their homeland in County Kerry.
I also began seeing rugged evidence which might explain why I haven't found any record for John Kelly in Ireland. On the records I accessed at the National Library of Ireland, the earliest dates began with baptisms on June 14, 1801. That sounded promising, as I've had several proposed dates for John Kelly's birth reaching back to that time period.
However, by the time I had reached baptisms in August, 1809, I encountered a problem: the next microfilmed page skipped to July, 1823, without any explanation. Gone, suddenly, was my chance to extract any hints about my target ancestor's baptismal sponsors, let alone the names of his parents, if he was indeed born in those earlier years.
For the Kelly records I am finding, I'm taking notes on the implied relationships. At some point, I'll sort these out and see if any patterns emerge. Before that can happen, though, I've got more transcribing to do—not to mention, a thorough search to see whether the missing years of this record set turn up anywhere else in digitized records at NLI or elsewhere.
