I am a looking for the same information. I am a descendant of Ann Monica Lane - Thomas' sister who also went to Quebec City but likely a bit later, around 1852, after Thomas was in Quebec. I don't have her birth details but believe she born between 1825 & 1830.
From a 1871 Quebec Cenus there was a woman ( aged 87) living with Thomas that appears to be his mother - Bridget Lane B 1784
The 1852 Census says Thomas b 1815 is from Limerick Ireland & Elizabeth Mangan b 1823 from Killrush Ireland.
I am interested in any info on their parents and where they may have lived. Ann Lane married a John Price and had a child Andrew William B 1851, before moving to Quebec where she had another child (Thomas Price) in 1855 that died at birth. She was then widowed and remarried a widower James Kennedy (of Ireland - potentially of co Tipperary) in 1859 in Quebec. She had 3 sons with James Kennedy.
They appear to have had a sister Mary Lane b. about 1820 - who married a Thomas Burke ( of Ireland) - they had a son Thomas born in Quebec around 1844 . The Quebec 1852 census for Mary Lane & Thomas Burke just says Ireland.
Ann Monica Lane & John Price do not appear in the Quebec 1852 census which supports that they came to Quebec later.
It would seem, that Thomas & Mary went to Quebec about the same in early 1840's.
Thomas Lane & Elizabeth Mangan's first son John Bernard was born in Quebec in 1843 & Michael in 1845 in Quebec.
Any information , or suggestions on how to find more information on the Lane familty would be appreciated.
Also looking to trace James Kennedy but have no information on him other than a birth about 1825. He married a Mary Morrisey and had a child Catherine Kennedy in Quebec in 1857. Mary died in 1859. He married the widow Ann Monica Lane in 1859 as well.
