It is my privilege to share my life (and Family Group Sheet!) with my wife and our four children. I became interested in my family tree when I was ten years old, patiently listening to many conversations between my father and various distant relatives. I began my own active research in 2006 and am looking forward to the time when my great grandchildren and their cousins are the ones asking me the questions!

Cultural Background

John Rosser has Irish ancestors.
Welsh flag
John Rosser has Welsh ancestors.
Scottish flag
John Rosser has Scottish Ancestors.
English flag
John Rosser has English ancestors.

I am Australian (between 4th-7th generation): all of my direct line ancestors had arrived in the colonies by 1860; a few were here before 1800.

However my Aussie 'tree' was ultimately 'transplanted' from British 'stock' - I claim descent from Welsh, Irish, Scottish and English migrants. These include convicts and soldiers (from before and after the 3rd Fleet), free settlers and economic migrants...on their shoulders I stand!


Besides working on documenting the lives of my own relatives, I like to give back to the wider WikiTree community in the following ways:

AustraliaGeneralMost of my activities within the Profile Improvement, Categorization, Connectors and One Name Studies projects relate to Australian profiles or categories.
Earl Grey's Famine Orphan Scheme 1848-1850
Team Leader
John Rosser is a member of the Earl Grey's Famine Orphan Scheme 1848-1850 Team.
• to create profiles for all of the orphans from the 'Pemberton' voyage
• to help improve the project's help pages, categories and resources.
CategorizationGeneralWorking with categories of the Migration, Shipping, Region and One Name Study streams (as related to profiles within 'Australian' projects):
• Adding profiles to categories
• Replacing categories on profiles with a narrower sub-category (if possible)
• Creating/setting up new categories (as required)
ConnectorsLost and FoundReconnecting profiles that became separated from their families during the upload of Tonkes_Morris_Ryles_Ellis.ged and improving them (as time permits)
One Name StudiesJackson Name Study
This profile is part of the Jackson Name Study.

• Adding and improving profiles of my 4xGGF and his descendants
• Ongoing DNA research
• Creation/maintenance of related categories (as required)
Profile ImprovementBioBuilder
Fountain Pen
John has written and improved ten profiles for the Biography Builders Challenge.
I frequently forget to post in the monthly challenge! I have started to log my work here.
SourcererI believe sources and accurate citations are vital for the health of our global tree - I am always adding new ones and/or improving existing ones on the profiles I touch.
Data DoctorManaging my own 'Suggestions' list and also correcting errors as I find them on other profiles. Clean-a-thon participant for 'Wizards of Aus'.

Hello John. My personal profile has volunteered information that we are 14 degrees apart in the Wikitree. Nothing very close. Several marriages. Two key links of the chain are Friedrich Schrapel and his son, Friedrich Wilhelm Schrapel, who farmed near Maitland in South Australia. Cheers, Steve

P.S. Another common interest. 2 of my GG-grandmothers were Earl Grey Orphans.

Hello John,

The Australia Project leadership team are carrying out a check-in to see how you are going in the project and especially to thank you for all your work on Australian profiles on WikiTree. We really value your participation.

Please could you get back to me by private message to let me know if you are happy with your current role and team involvement within the project or if you would like to do something additional or different. Currently we have you down as the Team Leader for the Earl Grey team and a member of the Profile Improvers, NSW and Categories teams. If you would like a change, you can check on the Australia Project page to see what other options there are.

It would also be great to hear any feedback and any suggestions that you have to improve the project. On a practical note, if you are a member of the google group, are you receiving messages ok?

I look forward to hearing from you.

Gillian, co-Leader, Australia Project

Hi John

As I have recently taken-on the role as the NSW Team Leader I thought I would just drop a quick note to thank you and to seek your input.

Firstly, I would love to know if there are any areas that you have an interest in looking at. Some of them might already be listed on the Free Space Page: Australia, Project Management - Proposed New Topics.

Secondly, I would love to know how you would prefer to be engaged and kept up-to-date. I would prefer to keep this as simple as possible and generating minimal emails etc. (if you’re like me you already receive too many!). Whatever your preferences are would be fine.

Thanks in advance

Peter, NSW Team Leader
