Hundreds of mourners give condolences to the families of four children killed ...

Hundreds of mourners have arrived at a memorial service for the four children hit and killed by an alleged drink-driver while on their way to buy ice cream.  

Abdallah siblings Sienna, 8, Angelina, 12, and Antony, 13, died at the scene in Oatlands, Sydney's north-west, on Saturday night alongside their 11-year-old cousin Veronique Sakr.

Samuel William Davidson, 29, was allegedly three times the legal blood alcohol limit when he drove into the group of seven children.  

A funeral for the Abdallah siblings will be held at the Our Lady of Lebanon Co-Cathedral in Harris Park on Monday morning. 

Devastated family and friends packed into that same church on Friday evening to pay their respects to the Abdallah and Sakr family.

HOW THE TRAGEDY UNFOLDED

Seven children were riding their bikes along the footpath of Beddington Road, Oatlands, just before 8pm on Saturday

* The children were on the way to buy ice cream when a Mitsubishi 4WD allegedly ploughed into them

*Residents raced to children's aid and frantically tried to save them while waiting for emergency services 

*Four children - including a boy, two of his sisters and a family friend - died at the scene

* Another boy, ten, was rushed to hospital with critical head injuries but is now in a stable condition

* Two girls were taken to hospital with non life-threatening injuries

*Male 4WD driver, a 29-year-old from Oatlands, underwent roadside breath test and allegedly returned positive result

*The alleged driver Samuel Davidson was arrested and taken to Castle Hill Police with his 24-year-old male passenger

*Davidson was charged with four counts of manslaughter

Mr Abdallah took Angelina, Sienna and their surviving sister Leanna, 10, on a weekend away to regional New South Wales in July last year.

Now, the memories of that happy holiday are getting him through the grief of losing three children.  

Videos from the weekend away show the three girls smiling and giggling as they ride motorbikes, take photos of unique Australian wildlife and watch movies by a roaring fire. 

Mr Abdallah shared the photos with Daily Mail Australia and said it was these memories that were helping him though his pain.

'They are really special memories of when I took them up to the farm last year. Just me and my girls,' he said.

'They loved being outdoors and you can see that from the videos and see what great kids they were'.  

Sienna - the youngest victim of Saturday night's horror accident - can be seen riding a child's motorbike for the first time.

'That's it, that's how you do it! You're going awesome,' Mr Abdallah tells his daughter encouragingly.
