Re Lawrence Duffy kin 1800 to 1850s

[GJDuffer]

My great great grandfather James Joseph Duffy born Monaghan 1832 (Carrickmacross?) arrived North America ~1850, ending up Cobourg Canada, near me in Toronto area.  His parents possibly Lawrence/Laurence and Sarah/Sara (Tracy/Lacy/Leary), Looking for leads to other family siblings to my James if any and siblings to his Lawrence (e.g. Patrick a brother or Patrick a father). So many 'James' and 'Patrick' to figure out. thanks

Welcome to RootsChat!

I can see that Laurence and Sarah are listed on his death certificate from 1911, but I cannot find any evidence he was born in Monaghan, so could you please provide your source for this.

If it was Carrickmacross and the family were Catholic then baptisms start 1836 (possibly too late for James Joseph but maybe siblings) and marriages from 1826 (although parents could have married before that date or in another parish)-

Note: these don't seem to be any earlier surviving records-

On Family Search there is a death of a 75 year old Laurence Duffy at Castle Blayney.  He would have been born about 1813 and possibly old enough to be the father of a child born 1832

This may be useful to help reduce the numbers of Lawrences you may have to search.

On Family Search there is a death of a 75 year old Laurence Duffy at Castle Blayney.

He was a shoemaker and living in Castleblayney. His son John Duffy was the informant.

my bigger mystery. Thru prabook.com which i found thru Carrickmacross search they identify Fr Francis Patrick Duffy (Irish Canadian American WW1 hero). Born/raised also in Cobourg Ontario 1871 as my great grandfather Daniel James Duffy (1862-1927). This piece says a Patrick Duffy (widower) and his 5 children emigrated to Canada 1845ish and one of these boys was the Patrick (married Mary Ready) who was the dad of Fr Francis Duffy (US army hero). My grandfather Daniel Norman Duffy (1889-1975) said personally to me that Fr Duffy was a cousin and was indeed a neighbour in Cobourg (proven by census 1861 to 1891). Not sure those two ever met though as Fr Duffy went to USA in 1890s. I have not found the blood link unless one of the priest's dad's brothers (of the widower's sons) was my great James Joseph Duffy. The described emigre Patrick (widower) may have had a second name, maybe Lawrence.
