To give you an idea of what I'm doing here's a small image (The full image is A2 but I don't want to post that as it has alot of personal information and photos of the living). Basically my daughters are in the centre, their father's family is the top half and their mother's family in the bottom half. I felt this way they could also see their cousins, aunts, uncles and grandparents fairly clearly.

The 6 white squares at the bottom are the McCabes and this is the family I'm trying to find more info on- any help would be appreciated.
Catherine McCabe was born in 1869 in Dundee, the daughter of Patrick McCabe and Rose Lynch. Her parents married in Dundee in 1868. She had a sister named Bridget who was born in 1870 but died in 1872. As a result of that birth her mother Rose died (in 1870). The father's occupation was given as "Foundry Labourer".
Try as I might I just cannot find Patrick and his two daughters (Catherine and Bridget) on the 1871 census. I can't find the survivors thereafter and cannot find a death for Patrick. Catherine married Peter Grattan in Dundee in 1896 and then I can find her in the 1901 census.
Even before Catherine was born I cannot find her parents. Using their marriage as a guide Patrick McCabe was born around 1846, the son of Michael McCabe (Labourer) and Bridget Smith. Rose McCabe, formerly Lynch, was born around 1842 to Peter Lynch (Farmer) and Catherine Clark.
I'm just trying to find the following. I suspect the parents of at least one may have been Irish so might not be located:
Patrick McCabe, b. c1846- where born and when did he die?
Rose McCabe, ms Lynch, (c1842-1870)- where born?
Michael McCabe- Where born and when?
Bridget McCabe, ms Smith- Where born and when?
Peter Lynch- Where born and when?
Catherine Lynch, ms Clark- Where born and when?
