Hi Dolly
This is a link to Robert Bloye's will on ancestry
http://www.rootschat.com/links/01hd5/ It is very detailed and, as it seems he had no children, there are lots of bequests to family members. It is also quite clear about relatiionships who is already deceased and shows a second marriage for Mary Laird widow of John Roman who has married a Billing. He was a rear Admiral when he made a codicil to his will.
I have been doing some more digging and I can see baptisms in Portsea for 4 of the children named in William Laird's will.
It is beginning to look like our John Laird was the son named in that will. I expect you have noticed that all the places we know of where events took place are ports.
The London marriage record does not give many clues although both John and Julia were single. The witnesses do not seem to be family members.
Do you think the older son William is the man who predeceased his father in 1809? The age seems to fit.
I realised after I posted that Saraj Julia did not marry. I can see her in the censuses up to her death except in 1851.
