Thanks to both Ballyatt.......G Jim, and aghadowey for your kind input.
Jim...I've had a look at your very interesting link, but don't see a commin link just now,( but have saved link for later).
aghadowey, it seems that 1855 is one of the few years that I don't have any pertinent births. I am now aware, whoever, that the information given on a BDM certificate, is only what the informant believes is correct. If he/she is lacking in certain information, then that is either omitted, or guessed.
Thanks once again
Gail
