Missing Downs/Downes

[pipj]

Hi All,

I wonder if anybody could help;- I'm looking for
William Down(e)s  c 1750 he married Mary (?) and they had three children as far as I can see;-
William  Chr 21/06/1772  Abdon    May have married Frances Preece 1806
Eleanor        30/08/1775   "          I think she may have married a John Brockley                                                                                                               
                                                     Tugford 06/10/1800   
Edward         27/07/1778   "         No further details

I can find any info of BMD for William and Mary and its keeping me up at nights now.
Please help a bleary eyed - going mentally insane and driving the family mad, fellow genealogist!!!!
Thanks loads
