I've also found the microfilm copy of the Detroit Border crossing report for my Joseph R. Watson. He crossed on May 24, 1912. At the bottom of the document there is an entry for "seaport and date of landing and name of steamship" (probably to Canada) and it is filled in "Quebec 6-1-06 ss Virginian". He's listed as single, an insurance agent, 28 years old and born in Beverly, England. He lists Toronto, Ontario as his last permanent residence. He lists his father Joseph R Watson, 332 Mimico Ave Toronto as his Canadian contact, and his destination address as Chicago, Illinois to his brother, Douglas Watson, 39 Ulster Ave.
I have had another look at this Border Crossing, see info below, father is just Jos Watson, there is something else written at an angle to the rest, looks like farming, but I cannot be certain. On this doc it dosen't show when he arrived in Canada or his brother Douglas or an address, is there another doc

I haven't found any Passenger Records for Joseph Watson snr for these crossings, so this causes problems as to whether these two Joseph's and Douglas are the same family as who we thought they were, but lets not discount them yet, Joseph Watson & Alice wasn't all that good at covering their tracks and we haven't started on tracing Douglas yet, who may well prove to be the key to these two Joseph's

Furthermore I have created another thread on Canada board asking for info regarding who was at 332 Mimico Ave, Toronto....
http://www.rootschat.com/forum/index.php?topic=685491.new#new scotiagirl are you able to assist with finding this information please

I have also asked
broadgate on the Watson thread to ask William in Canada if he has any knowledge of his grandfather Joseph Watson residing at 332 Mimico Ave.
broadgate has added some photographs of Alice on the Watson thread if anyone would like to look at them.
scotiagirl, I know you was hoping for a death but we have to find the right Joseph Watson then we may be able to find his death.
