If he was still in Ayrshire in 1861 there's a possible  here~

Muirlaught, Ardrossan

William Allan, 69, farmer of 135 acres employing 1 boy, b. Ardrossan
,,,,,,,,

Willim McIllwain, servant, 14, farmers boy, b. Ardrossan

[Rosinish]

1861 (SP) looks as though parents are still around but aged by almost 20 yrs instead of 10;

MCILWAIN WILLIAM 59
576/1 4/ 5
Ardrossan Old, Ayr

Others under same ref. no.

Rose Ann 58
Mary 15 error 
Hugh 10

In the 1861, Ardrossan, William and Rose Ann/Rosina are down as Mcilwain  and only Hugh is with them.

Gadget, I must have erred on 1861 (it's my trait)

Mary/Marion is with her uncle Roger Brown (70, b. Ireland) in Kirk Road, Ardrossan

Mary McIlwain, niece, 17, b. Ireland

Annie - I reckon that this is the most likely family, with the names all mixed up. William, jnr, either didn't know the names of his parents or was confused by the ceremony or something else.

Added - I had a good look at the Irish records earlier and didn't find anything so far. Maybe a search for some of the other children's baptisms would turn up something. I think I found a Rosanna Brown bpt Dublin circ 1803 but nothing much else.
