Thank you for your kind offer, Jean.
I have a Thomas Robertson and wife Jean living around the Dundee area (as far as I know). Sorry I don't know their ages but I would guess they would be in their 40s. A son Thomas was born approx 1861. He wasn't married at the time of the census but I don't know if he was still living at home. Other children if any are unknown.
I also have Henry Alexander Campbell, wife Mary with any of the following children: Christina 25, Archibald 23, Mary 21, Henry 19, Allan 17, Adam 15, Catherine 13, Robert 11, Dugald 8 and Margaret 7. I think the family could have been living at Monifieth as this is where Catherine was born.
Sorry for waffling on for so long. Thank you once again. I am in Australia so if there is anything I can help you with here please let me know.
Rob.
