Thanks for the heads up about the Familysearch link Re: looking for BT's. While not nearly as easy to find information directly (No indexes) there is much more info than Genuki Indexes provide.
I'm still trying to gather info from them, with some success, but also issues. By flipping pages and reading the entries as I go, you see Henry Salkeld of Lowlights, labourer, died May 2 1808, buried 6 May 1808, aged 44 years. (Tynemouth Bishops transcripts page 618 of 835). By math, (if my math is right) would place his birth between May 3rd 1763 and May 2nd 1764. If I go back to the bishops transcripts for those years for baptisms there's a jump in the dates from the 29 Dec 1762 and 1 June 1769 (between pages 7 and 10 of 835 pages) right where I would like to look. Is there anywhere else to look for these missing pages (hopefully online)?
