Wwell, turns out poppler was already installed, and after I figured out how to invoke it, results were not so great. Still generates multiple files (one per page), and here's the first few lines of the html generated for the pdf table:
<DIV style="position:absolute;top:113;left:31"><nobr><span class="ft00"><b>LAST NAME</b></span></nobr></DIV>
<DIV style="position:absolute;top:113;left:187"><nobr><span class="ft00"><b>FIRST NAME</b></span></nobr></DIV>
<DIV style="position:absolute;top:113;left:340"><nobr><span class="ft00"><b>MIDDLE</b></span></nobr></DIV>
<DIV style="position:absolute;top:113;left:458"><nobr><span class="ft00"><b>SPOUSE</b></span></nobr></DIV>
<DIV style="position:absolute;top:113;left:768"><nobr><span class="ft00"><b>PROBATE DATE</b></span></nobr></DIV>
<DIV style="position:absolute;top:113;left:931"><nobr><span class="ft00"><b>BOOK</b></span></nobr></DIV>
<DIV style="position:absolute;top:113;left:1009"><nobr><span class="ft00"><b>PAGE</b></span></nobr></DIV>
Not exactly what I was expecting, I was hoping for something like this:
<table>
<tr align="center">
<td>Bride</td>
<td>Groom</td>
<td>Date</td>
<td>Page</td>
<td>Official</td>
</tr>
<tr>
<td>ABBOTT, Mollie</td>
<td>Norton, James N.</td>
<td>09 Aug 1877</td>
<td>60, 188</td>
<td>Thomas White JP</td>
</tr>
but... with some judicious "find and replace" in kwrite, it might be usable. Otherwise it looks like it's going to be a long and tedious process... unless I can track down the original author and get the source files...
Thanks everyone, still looking, before I begin any monumental manual conversions...
